Explanation:

(a) The outlet velocity of the steam is approximately 480 m/s.

(b) The outlet volumetric flow rate of the steam is approximately \(0.413 m^3/s.\)

To determine the outlet velocity and volumetric flow rate of the steam, we can apply the principles of conservation of mass and energy. Under steady flow conditions, the mass flow rate of the steam remains constant.

Using the equation of continuity, which states that mass flow rate is equal to the product of density, velocity, and cross-sectional area, we can calculate the outlet velocity. Given the mass flow rate of 1.5 kg/s, the density of the steam can be determined using steam tables.

To find the outlet velocity, we divide the mass flow rate by the product of density and cross-sectional area. The cross-sectional area can be calculated using the known inlet velocity and the fact that the area is constant throughout the nozzle.

For the outlet volumetric flow rate, we can use the mass flow rate and the density of the steam to convert it to the corresponding volumetric flow rate. Volumetric flow rate is the mass flow rate divided by density.

By applying the given values and performing the necessary calculations, we can find that the outlet velocity of the steam is approximately 480 m/s and the outlet volumetric flow rate is approximately \(0.413 m^3/s.\)

To calculate the specific weight, density, and specific gravity of a liquid that weighs 7 N in a 1 liter container, we need to know the acceleration due to gravity in the particular location where the measurement is being taken.

Assuming a standard acceleration due to gravity of 9.81 m/s^2:

Specific weight: The specific weight of a substance is its weight per unit volume.

Specific weight = weight / volume

In this case, the weight of the liquid is given as 7 N, and the volume is 1 liter, which is equivalent to 0.001 cubic meters. Therefore, the specific weight is:

Specific weight = 7 N / 0.001 m^3 = 7000 N/m^3

Density: The density of a substance is its mass per unit volume.

Density = mass / volume

We can calculate the mass of the liquid by dividing the weight by the acceleration due to gravity:

Mass = weight / acceleration due to gravity = 7 N / 9.81 m/s^2 = 0.714 kg

Therefore, the density of the liquid is:

Density = 0.714 kg / 0.001 m^3 = 714 kg/m^3

Specific gravity: The specific gravity of a substance is the ratio of its density to the density of a reference substance, typically water at 4°C.

Specific gravity = density of substance / density of water

The density of water at 4°C is approximately 1000 kg/m^3. Therefore, the specific gravity of the liquid is:

Specific gravity = 714 kg/m^3 / 1000 kg/m^3 = 0.714

Technical drawing, also known as drafting or draughting, is the act and discipline of making detailed drawings. These drawings visually communicate how something works or how it is to be made.

a)  The initial and final temprature are 99.61°C and T3 = 259.07°C

b)   The mass of liquid water when the piston first start moving is 0g

Using the data provided:

Initial Pressure = P1 = 125kPa

Mass of Saturated Vapor Liquid = m = 5kg

Initial Mass of Liquid water = mf = 2kg

Initial Mass of Vapor = mg = 3kg

The temperature for a mixture of liquid steam saturated with water according to the thermodynamic table is:

T₁ = 99.61°C

The specific volume is:

vf = 0.001043m³/kg

And the saturated volume is:

vg = 1.6941m³/kg

Therefore, the volume in state 1 will be equal to:

V1 = mfvf + mgvg

V1 = (2kg)(0.001043m³/kg) + (3kg)(1.6941m³/kg)

V1 = 5.084m³

In state 3 then the volume will be equal to:

V3 = 1.2V1

V3 = 1.2(5.084m³)

V3 = 6.1008m³

Then the specific volume will be equal to:

v3 = V₃/m

v3 = 6.1008m³/5kg

v3 = 1.2202m³/kg

For a pressure of 300 kPa and the previous specific volume found through the thermodynamic table, the value of the temperature is:

T3 = 259.07°C

Question b) When the piston first stats moving at P₂ = 300kPa and V₂ = V₁ = 5.084m³

v₂ =V₂/m

v₂ = 5.084m³/5kg

v2 = 1.0168m³/kg

While at 300 kPa the value of the vapor saturated vg = 0.88578m³/kg This implies that the condition is met:

v2 > vg

Therefore, no liquid is there in-cylinder when piston stats moving, mf = 0kg

The maximum collector voltage that keeps the collector-base junction reverse biased is determined by the breakdown voltage of the junction, which is the voltage at which the junction.

The collector-base junction in a bipolar junction transistor (BJT) acts as a switch that allows or prohibits current flow between the collector and base terminals. To maintain the reverse bias configuration, the voltage across the collector-base junction should remain below the breakdown voltage of the junction. The breakdown voltage, also known as the peak inverse voltage (PIV), is the maximum voltage that the junction can withstand in reverse bias before becoming forward-biased and allowing current to flow.

If the collector voltage exceeds the breakdown voltage, the junction will conduct current and may become damaged, leading to permanent degradation or failure of the device. The exact value of the breakdown voltage depends on the specific BJT and its manufacturing process and can be found in the datasheet for the device. It is important to consider the breakdown voltage when designing circuits with BJTs to avoid exceeding the limit and damaging the device.

The output of the RC filter when the input is x(t) = rect((t²-D/2²)/(RC)) is a scaled and delayed version of the input rectangular pulse.

When the input to the RC filter is a rectangular pulse, x(t) = rect((t²-D/2²)/(RC)), the output can be computed by convolving the input signal with the impulse response of the RC filter.

Convolution is a mathematical operation that combines two signals to produce a third signal. In this case, we are convolving the rectangular pulse with the impulse response of the RC filter. The impulse response of the RC filter is given by h(t) = encu(t)/(RC), where en is the unit step function.

To compute the convolution, we can express the rectangular pulse as a sum of unit step functions and apply the properties of convolution. This involves integrating the product of the impulse response and the shifted rectangular pulse over the range of integration.

The result of the convolution is a scaled and delayed version of the rectangular pulse. The scaling factor is determined by the values of R and C, and the delay is determined by the time constant RC. The output will have a similar shape as the input rectangular pulse but may be stretched or compressed in time.

Answer:

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

The wind turbine makes a daily revenue of 1736.75 US dollars.

Explanation:

First, we have to determine the stored energy of wind (\(E_{wind}\)), measured in Joules, by means of definition of Kinetic Energy:

\(E_{wind} = \frac{1}{2}\cdot \dot m_{wind}\cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1)

Where:

\(\dot m_{wind}\) - Mass flow of wind, measured in kilograms per second.

\(\Delta t\) - Time in which wind acts in a day, measured in seconds.

\(v_{wind}\) - Steady wind speed, measured in meters per second.

By assuming constant mass flow and volume flows and using definitions of mass and volume flows, we expand the expression above:

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot \dot V_{air} \cdot \Delta t \cdot v_{wind}^{2}\) (Eq. 1b)

Where:

\(\rho_{air}\) - Density of air, measured in kilograms per cubic meter.

\(\dot V_{air}\) - Volume flow of air through wind turbine, measured in cubic meters per second.

\(E_{wind} = \frac{1}{2}\cdot \rho_{air}\cdot A_{c}\cdot \Delta t\cdot v_{wind}^{3}\) (Eq. 2)

Where \(A_{c}\) is the area of the wind flow crossing the turbine, measured in square meters. This area is determined by the following equation:

\(A_{c} = \frac{\pi}{4}\cdot D^{2}\) (Eq. 3)

Where \(D\) is the diameter of the wind turbine blade, measured in meters.

If we know that \(\rho_{air} = 1.25\,\frac{kg}{m^{3}}\), \(D = 100\,m\), \(\Delta t = 86400\,s\) and \(v_{wind} = 8\,\frac{m}{s}\), the stored energy of the wind in a day is:

\(A_{c} = \frac{\pi}{4}\cdot (100\,m)^{2}\)

\(A_{c} \approx 7853.982\,m^{2}\)

\(E_{wind} = \frac{1}{2}\cdot \left(1.25\,\frac{kg}{m^{3}} \right) \cdot (7853.982\,m^{2})\cdot (86400\,s)\cdot \left(8\,\frac{m}{s} \right)^{3}\)

\(E_{wind} = 2.171\times 10^{11}\,J\)

Now, we proceed to determine the quantity of energy from wind being used by the wind turbine in a day (\(E_{turbine}\)), measured in joules, with the help of the definition of efficiency:

\(E_{turbine} = \eta\cdot E_{wind}\) (Eq. 4)

Where \(\eta\) is the overall efficiency of the wind turbine, dimensionless.

If we get that \(E_{wind} = 2.171\times 10^{11}\,J\) and \(\eta = 0.32\), then the energy is:

\(E_{turbine} = 0.32\cdot (2.171\times 10^{11}\,J)\)

\(E_{turbine} = 6.947\times 10^{10}\,J\)

The wind turbine generates \(6.947\times 10^{10}\) joules of electricity daily.

A kilowatt-hours equals 3.6 million joules. We calculate the equivalent amount of energy generated by wind turbine in kilowatt-hours:

\(E_{turbine} = 6.947\times 10^{10}\,J\times\frac{1\,kWh}{3.6\times 10^{6}\,J}\)

\(E_{turbine} = 19297.222\,kWh\)

The wind turbine generates \(19297.222\) kilowatt-hours of electricity daily.

Lastly, the revenue generated per day can be found by employing the following:

\(C_{rev} = c\cdot E_{turbine}\) (Eq. 5)

Where:

\(c\) - Unit price, measured in US dollars per kilowatt-hour.

\(C_{rev}\) - Revenue generated by the wind turbine in a day, measured in US dollars.

If we know that \(c = 0.09\,\frac{USD}{kWh}\) and \(E_{turbine} = 19297.222\,kWh\), then the revenue is:

\(C_{rev} = \left(0.09\,\frac{USD}{kWh} \right)\cdot (19297.222\,kWh)\)

\(C_{rev} = 1736.75\,USD\)

The wind turbine makes a daily revenue of 1736.75 US dollars.

This formula describes the distance from the building that Prof Murthy must be when you release the egg

Explanation:

First, we need to find the time required by the egg to reach the head of Professor. For that purpose, we use 1st equation of motion in vertical form:

Vf = Vi + gt

where,

Vf = Velocity of egg at the time of hitting head of the Professor

Vi = initial velocity of egg = 0 m/s  (Since, egg is initially at rest)

g = acceleration due to gravity

t = time taken by egg to come down

Therefore,

Vf = 0 + gt

t = Vf/g   ----- equation (1)

Now, we use 3rd euation of motion for Vf:

2gs = Vf² - Vi²

where,

s = height dropped = H - h

Therefore,

2g(H - h) = Vf²

Vf = √[2g(H - h)]

Therefore, equation (1) becomes:

t = √[2g(H - h)]/g

t = √[2(H - h)/g]

Now, consider the horizontal motion of professor. So, the minimum distance of professor from building can be found out by finding the distance covered by the professor in time t. Since, the professor is running at constant speed of v m/s. Therefore:

s = vt

s = v√[2(H - h)/g]

This formula describes the distance from the building that Prof Murthy must be when you release the egg

Answer:

To solve this problem, we can use the conservation of energy principle. The potential energy at A is equal to the kinetic energy at B, C, and D. Since the chute is smooth, there is no friction and no energy is lost due to work done against frictional forces.

At point A, the package has only potential energy, which is given by mgh, where m is the mass of the package, g is the acceleration due to gravity, and h is the height of point A above the horizontal plane. The potential energy at A is converted to kinetic energy at point B, so we can equate these two energies to find the velocity of the package at B.

mgh = (1/2)mvB^2

where vB is the velocity of the package at point B.

Solving for vB, we get:

vB = sqrt(2gh)

Substituting the given values, we get:

vB = sqrt(2*32.2 ft/s^2 * 10 ft) = 20 ft/s

At point C, the potential energy is still the same, but the kinetic energy is different because the velocity of the package has changed. We can equate the potential energy at A to the kinetic energy at point C to find the velocity of the package at C.

mgh = (1/2)mvC^2

where vC is the velocity of the package at point C.

Solving for vC, we get:

vC = sqrt(2gh/3)

Substituting the given values, we get:

vC = sqrt(2*32.2 ft/s^2 * 10 ft/3) = 19 ft/s

At point D, the potential energy is still the same, but the kinetic energy is different because the velocity of the package has changed again. We can equate the potential energy at A to the kinetic energy at point D to find the velocity of the package at D.

mgh = (1/2)mvD^2

where vD is the velocity of the package at point D.

Solving for vD, we get:

vD = sqrt(2gh/2)

Substituting the given values, we get:

vD = sqrt(2*32.2 ft/s^2 * 10 ft/2) = 22.6 ft/s

To find the normal force at point C, we need to resolve the weight of the package into its components along the normal
