The true statement concerning electrical systems is that lights and radios use the electrical system for power. Among the given options, option c) "lights and radios use the electrical system for power" is the true statement concerning electrical systems.

In modern electrical systems, lights and radios (among other components) rely on the electrical system for power. Electrical systems in various domains, such as aviation or general household applications, provide the necessary electrical energy to operate these devices. Lights, whether they are interior lights or external lights on vehicles, are powered by the electrical system. Similarly, radios and other electronic devices require electrical power to function, and they draw power from the electrical system.

On the other hand, option a) "the master switch creates a current that is supplied to the electrical system" is not a true statement. The master switch does not create the current; rather, it controls the flow of electrical power within the system. It acts as a control mechanism to enable or disable the power supply to various components within the electrical system.

Option b) "the airspeed indicator is driven by the electrical system" is also not a true statement. The airspeed indicator in aviation is typically driven by other mechanisms, such as pitot tubes or air pressure sensors, which measure the airspeed independently of the electrical system.

Explanation:

The three components that are combined to form a Bridge ID (Bridge Identifier) in a network bridge are the Bridge Priority, MAC Address, and VLAN ID.

In computer networking, a bridge is a device that connects multiple network segments together, allowing them to communicate as a single network. Each bridge in a network is assigned a unique Bridge ID, which helps in identifying and distinguishing it from other bridges.

The Bridge ID is a 64-bit value that consists of three components:

1. Bridge Priority: It is a 16-bit value used to determine the priority of the bridge in the network. Lower values indicate higher priority. The Bridge Priority is typically assigned by the network administrator and is used in the Spanning Tree Protocol (STP) to elect a root bridge.

2. MAC Address: The MAC (Media Access Control) Address is a unique identifier assigned to the network interface card (NIC) of a bridge. It is a 48-bit value that uniquely identifies the bridge in the network. The MAC Address is an essential component of the Bridge ID as it helps in identifying the source of network traffic.

3. VLAN ID: The VLAN (Virtual Local Area Network) ID is a 12-bit value that identifies a specific VLAN to which the bridge belongs. VLANs are used to segment a network into multiple logical networks, allowing for better management and control. The VLAN ID is included in the Bridge ID to associate the bridge with a particular VLAN.

By combining the Bridge Priority, MAC Address, and VLAN ID, a unique Bridge ID is formed, which helps in identifying and differentiating bridges in a network.

The Bridge ID in a network bridge is formed by combining the Bridge Priority, MAC Address, and VLAN ID. These components work together to create a unique identifier for each bridge, enabling effective network communication and management.

Compared with powder-actuated nailers, electric and pneumatic nailers do not require certification.

Powder-actuated, electrical, and pneumatic nailers are all tools commonly used in construction and carpentry for fastening materials together. Each type of nailer operates differently and has its own advantages and applications. Here's a brief explanation of each:

Powder-Actuated Nailers : These nailers, also known as "powder-actuated tools" or "gun-powered nailers," use explosive charges to drive nails into hard materials like concrete, steel, or masonry. They are typically used in commercial construction or heavy-duty applications. A powder-actuated nailer consists of a barrel, firing pin, and a chamber for loading the charge. When the trigger is pulled, the firing pin strikes the charge, causing it to explode and propel the nail into the material.

Electrical Nailers : Electrical nailers, also called electric nail guns or corded nailers, rely on an electric power source to drive nails. They are generally lighter and more portable than their pneumatic counterparts. Electrical nailers use an electric motor or solenoid mechanism to push the nail forward with significant force when the trigger is squeezed. They are commonly used for interior finishing work, such as attaching baseboards, trim, or cabinetry.

Pneumatic Nailers : Pneumatic nailers, also known as air-powered nail guns or compressed air nailers, use compressed air to drive nails. They require an air compressor to generate the necessary power. Pneumatic nailers are widely used in construction and woodworking due to their versatility, power, and speed. They can drive nails into various materials, including wood, drywall, and some metals. They are available in different styles, such as framing nailers, finish nailers, and brad nailers, each suitable for specific tasks.

Answer:

Weight Percentage of Ash = 3.4

Explanation:

Given - Coal containing 21% ash is completely combusted, and the ash is 100% removed in a water contact scrubber. If 10,000 kg of coal is burned per hour with a scrubber flow rate of 1.0 m3/min.

To find - the weight percentage of the ash in the water/ash stream leaving the scrubber is most nearly ?

Solution -

Given that,

Coal Burned Rate = 10,000 kg/hr

                              = \(\frac{10,000}{60 min} * 1 hr *\frac{kg}{hr}\)

                              = 166.6666 kg/min

⇒Coal Burned Rate = 166.6666 kg/min

Now,

Given that,

Ash content in coal = 21 %

⇒Ash in (coal that burned) = 166.6666 × \(\frac{21}{100}\) kg/min

                                             = 34.9999 ≈ 35 kg/min

⇒Ash in (coal that burned) = 35 kg/min

Now,

We know,

Density of water = 1000 kg/m³

Now,

Water flow Rate = \(1\frac{m^{3} }{min} * density\)

                           = 1000 kg/min

⇒Water flow Rate = 1000 kg/min

Now,

Total Mass flow Rate of (Water + Ash stream) = ( 1000 + 35) kg/min

                                                                           = 1035 kg/min

⇒Total Mass flow Rate of (Water + Ash stream) = 1035 kg/min

So,

Weight Percentage of Ash = (Weight of Ash ÷ Total weight of Stream) × 100

                                            = (35 ÷ 1035) × 100

                                            = 3.38 ≈ 3.4

∴ we get

Weight Percentage of Ash = 3.4

Answer:

To solve this problem, we need to use the Reynolds number, the Prandtl number, and the Darcy friction factor. The Reynolds number is a dimensionless number that describes the flow regime of the fluid, the Prandtl number characterizes the ratio of momentum diffusivity to thermal diffusivity, and the Darcy friction factor describes the frictional losses in the pipe.

(a)

For pressurized water at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 997 kg/m^3 (density of water at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (997 * 0.000314) = 3.18 m/s

The Reynolds number for water is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.000283 Pa s (dynamic viscosity of water at 366 K)

Re = (997 * 3.18 * 0.02) / 0.000283 = 2.24e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 2.24e5 * 0.02 = 224 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For water at 366 K, Pr = 5.5 and we can estimate Nu using the Dittus-Boelter correlation:

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Nu = 0.023 * (2.24e5)^(4/5) * 5.5^(0.4) = 244

L_th = 0.05 * 2.24e5 * 5.5 * 0.02 / 244 = 3.6 m

For engine oil (unused) at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 890 kg/m^3 (density of engine oil at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (890 * 0.000314) = 3.79 m/s

The Reynolds number for engine oil is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.0003 Pa s (dynamic viscosity of engine oil at 366 K)

Re = (890 * 3.79 * 0.02) / 0.0003 = 4.72e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 4.72e5 * 0.02 = 472 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For engine oil at 366 K, Pr = 130 and we can estimate Nu using the Dittus-Boelter correlation:

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Nu = 0.023 * (4.72e5)^(4/5) * 130^(0.4) = 2600

L_th = 0.05 * 4.72e5 * 130 * 0.02 / 2600 = 7.2 m

For NaK (22%/78%) at 366 K and a flow rate of 0.01 kg/s, we can calculate the mean velocity as follows:

v = m_dot / (rho * A), where

m_dot = 0.01 kg/s (mass flow rate)

rho = 1100 kg/m^3 (density of NaK at 366 K)

A = pi * (0.02 m)^2 / 4 = 0.000314 m^2 (cross-sectional area of the tube)

v = 0.01 / (1100 * 0.000314) = 2.87 m/s

The Reynolds number for NaK is:

Re = (rho * v * D) / mu, where

D = 0.02 m (diameter of the tube)

mu = 0.0018 Pa s (dynamic viscosity of NaK at 366 K)

Re = (1100 * 2.87 * 0.02) / 0.0018 = 3.48e5

Using the Reynolds number, we can estimate the hydrodynamic entry length using the following equation:

L_hyd = 0.05 * Re * D

L_hyd = 0.05 * 3.48e5 * 0.02 = 348 m

For the thermal entry length, we use the following equation:

L_th = 0.05 * Re * Pr * D / Nu

where Pr is the Prandtl number and Nu is the Nusselt number. For NaK at 366 K, Pr = 0.013 and we can estimate Nu using the Sieder-Tate correlation:

Nu = 0.027 * Re^(4/5) * Pr^(0.43)

Nu = 0.027 * (3.48e5)^(4/5) * 0.013^(0.43) = 67.3

L_th = 0.05 * 3.48e5 * 0.013 * 0.02 / 67.3 = 0.008 m

(b)

For water and engine oil, the mass flow rate is given as 0.01 kg/s, and the mean velocity is given as 0.02 m/s.

For water at 300 K:

rho = 996.6 kg/m^3 (density of water at 300 K)

mu = 0.000547 Pa s (dynamic viscosity of water at 300 K)

Pr = 7.02 (Prandtl number of water at 300 K)

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

Re = (rho * v * D) / mu = (996.6 * 0.02 * 0.02) / 0.000547 = 1445

Nu = 0.023 * Re^(4/5) * Pr^(0.4) = 0.023 * (1445)^(4/5) * 7.02^(0.4) = 426.5

L_hyd = 0.05 * Re * D = 0.05 * 1445 * 0.02 = 14.45 m

L_th = 0.05 * Re * Pr * D / Nu = 0.05 * 1445 * 7.02 * 0.02 / 426.5 = 0.021 m

For water at 400 K:

rho = 958.4 kg/m^3 (density of water at 400 K)

mu = 0.000294 Pa s (dynamic viscosity of water at 400 K)

Pr = 4.41 (Prandtl number of water at 400 K)

Nu = 0.023 * Re^(4/5) * Pr^(0.4)

The average temperature throughout the winding is approximately 137.5°C.

To solve this problem, we need to use the formula for the resistance-temperature relationship of copper:

R2 = R1 [1 + α(T2 - T1)]

where R1 is the resistance of the winding at the initial temperature T1, R2 is the resistance of the winding at the final temperature T2, and α is the temperature coefficient of resistance of copper.

We can rearrange the formula to solve for the final temperature T2:

T2 = (R2/R1 - 1) / α + T1

First, we need to calculate the resistance of the winding at the initial temperature T1 = 17°C:

R1 = V1 / I1 = 440 V / 2.3 A = 191 Ω

Next, we need to calculate the resistance of the winding at the final temperature, which we can do using Ohm's law:

R2 = V1 / I2 = 440 V / 1.9 A = 231.6 Ω

Now we can plug in these values into the formula for T2:

T2 = (231.6/191 - 1) / 0.00426 + 17 = 137.5°C

The magnitude of FB is 700 N, and its orientation is 59.5° from the x-axis.

Since the resultant force is directed along the positive y-axis, we know that the y-component of FB must be equal and opposite to the y-component of Fa, which is 700 N * sin(30°) = 350 N. Therefore, the magnitude of the y-component of FB is also 350 N.

To find the magnitude of FB itself, we can use the Pythagorean theorem:

\(FB^2 = (y-component of FB)^2 + (x-component of FB)^2\)

\(FB^2 = (350 N)^2 + (FBx)^2\)

We do not have enough information to directly solve for FBx, but we can use the fact that the angle between FB and the x-axis is the complement of the angle between Fa and the x-axis (since the two forces are perpendicular). Therefore,

tan(θ) = FBx / 350 N

where θ is the angle between FB and the x-axis.

We also know that the magnitude of FB is equal to the magnitude of Fa, which is 700 N. Therefore, we have:

\(FB^2 = FBx^2 + (350 N)^2 = (700 N)^2\)

Solving for FBx, we get:

\(FBx = sqrt((700 N)^2 - (350 N)^2) = 606 N\)

Using the equation for tan(θ), we get:

θ = arctan(FBx / 350 N) = 59.5°

Therefore, the magnitude of FB is 700 N, and its orientation is 59.5° from the x-axis.
