How many grains are on the surface of the head of a pin? assume that the head of a pin is spherical with a 1-mm diameter and has an astm grain size of 10

Answer:

a) -505.229 kJ/Kg

b) -1.724 kJ/kg

Explanation:

T1 = 400°C

P1 = 3 MPa

P2 = 125 kPa

work output   = 530 kJ/kg

surrounding temperature = 20°C = 293 k

A) Calculate heat transfer from Turbine to surroundings

Q = h2 + w - h1

h ( enthalpy )

h1 = 3231.229 kj/kg

enthalpy at P2

h2 = hg = 2676 kj/kg

back to equation 1

Q = 2676 + 50 - 3231.229  = -505.229 kJ/Kg  ( i.e.  heat is lost )

b) Entropy generation

entropy generation = Δs ( surrounding )  + Δs(system)

                                =  - 505.229 / 293   + 0

                                = -1.724 kJ/kg

Based on the table in part a., the CO2e emissions in 2019 are as follows:ActivityDataEmission FactorEmission ScopeCO2e Emissions Electricity Consumption (kWh)100,000,0000.0004773Scope 23,677,500Natural Gas Consumption (MCF)2,000,0000.0031964Scope 11,605,296Motor Gasoline Consumption (gal)20,5006.80E-03Scope 12,719Light Diesel Consumption (gal)10,0009.76E-03Scope 12,413New Warehouse Electricity Consumption (kWh)2,000,0000.0004773Scope 11,918,212Solar Panel Electricity Production (kWh)500,0000.0004773Scope 29,136Replacement of Gasoline vehicles (gal)17,5007.12E-03Scope 13,002Conversion of Diesel Trucks to 20% BioDiesel (gal)10,0007.72E-03Scope 13,062LED Lighting Retrofit (kWh)1,000,0000.0004773Scope 11,918Scope 3: 31,200Scope 2: 23,677,500Scope 1: 47,439,385Total TV's CO2e Emissions in 2019: 102,317,085

Observations:From the table, it can be observed that the Scope 1 emissions have significantly increased from 2018 to 2019, mainly due to the increased consumption of motor gasoline, addition of bio-diesel consumption, and increased energy consumption from solar panels. At the same time, the Scope 3 emissions have also increased, primarily due to the replacement of gasoline-fueled cars with hybrids.

However, the Scope 2 emissions have not changed since the electricity consumption remained the same and no emissions were produced due to Solar panels used. Assumptions:All the vehicles have the same mileage per year in both years.All the gasoline is used, and there is no evaporation.The new warehouse was used for the whole year.The Climate Registry 2019 Default Emission Factors were used.

In computer terminology, actions such as clicking and double-clicking are called events. An event refers to any action that a user performs on a computer such as clicking a button, typing a key, or moving the mouse.

The computer system identifies these actions as input events, which it receives and then interprets. The purpose of events is to trigger specific actions in the system, and they can be handled using event handlers. An event handler is a specific procedure that is invoked when an event occurs. It contains instructions on what to do when a particular event occurs. Events are used widely in programming, especially when it comes to developing user interfaces. User interface elements such as buttons and text boxes can be designed to respond to events such as clicking or double-clicking. When an event is triggered, the user interface element responds by executing a specific action.

The allowable normal strength in the c-section is 48000 pounds per square inch.

The allowable stress depends on both the factor of safety imposed on the object and the yield strength or stress at which an object will be permanently damaged. To calculate the allowable normal strength we can divide the yield strength by the factor of safety.

To determine the allowable normal strength output we can use this equation below:

The allowable normal strength = The number yield strength : A stress-concentration factor

The number yield strength is 84 kpsi.

Then convert kpsi to psi : 84 kpsi = 84000 psi

A stress-concentration factor is 1.75

No, the physical address 346E0 cannot be the starting address for a segment. This is because the starting address of a segment must be aligned with the segment's size or boundary, which is determined by the processor's architecture.

Segment boundaries are defined by 16-byte or 4-byte boundaries, depending on the segment's use. Therefore, the starting address of a segment must be a multiple of 16 or 4, respectively, depending on the segment type.

In the given address 346E0, the last digit is 0, which indicates that it is a multiple of 16. However, we do not have enough information about the processor architecture and segment size to determine whether this is an appropriate starting address for a segment.

To design LQR Quadcopter in simulink, we will require the following steps: Step 1: Mathematical model derivation To obtain the dynamic model of a Quadcopter.

Step 1: Mathematical Model Derivation There are four main components of the Quadcopter mathematical model, which are: Rotation angle equations of motion: The pitch angle (ϕ), the roll angle (θ), and the yaw angle (ψ) are the rotation angles of the Quadcopter. These angles have to satisfy the equations of motion to produce stable Quadcopter control. Position equations of motion: The position of the Quadcopter in space can be represented by three coordinates (X, Y, and Z). These three coordinates must also satisfy the equations of motion to maintain the Quadcopter's stability. Rotational dynamics: To calculate the rotational dynamics of the Quadcopter, one must determine its moments of inertia and angular velocity.

Step 1: Mathematical Model Derivation The mathematical model of a Quadcopter is derived using the following equations: Rotation angle equations of motion: ϕ = φ θ = θ ψ = ψ Position equations of motion: X = X Y = Y Z = Z
Rotational dynamics: Jx [p dot - (q sin(ϕ) + r cos(ϕ))] =  Jy [q dot - (p sin(ϕ) + r cos(ϕ))] = M Jz [r dot - (q sin(ϕ) + p cos(ϕ))] = N Translational dynamics After completing the LQR design, the block diagrams are used to design the system in Simulink. Different blocks are used to represent the various components of the control system. The final block diagram provides the simulation results for the system.

The viscosity of the fluid at each temperature:

1) the source voltage Vs referred to the low voltage side is Vs = 480 V

2) the transmission line current iTL is 26.67 - j20 A

3) the load current il is  0.00833 + j0.00625 A

4) the voltage drop across the transmission line Vdrop is 4.8006 + j5.3248 V

5) the load voltage VL is 48 V

To solve the given problem, we'll use the given information and apply relevant formulas. Let's go through each step:

1) Finding the source voltage Vs referred to the low voltage side:

We know that the turns ratio of the transformer is 10:1. Therefore, the voltage transformation ratio is also 10:1. So, we can write:

Vs/V2 = Ns/N2 = 10

Vs/4800 = 10

Vs = 4800/10

Vs = 480 V

2) Finding the transmission line current iTL:

The transmission line current can be calculated using Ohm's Law:

iTL = V2 / Zline

iTL = 4800 / (0.18 + j0.24)

iTL = (4800 / 0.18) - j(4800 / 0.24)

iTL = 26.67 - j20

3) Finding the load current il:

To find the load current, we can use the apparent power formula:

S = V * I*

Where S is the complex power, V is the voltage, and I* is the conjugate of the current.

Given that the apparent power S is 4 + j3 VA, and the voltage V is 480 V, we can solve for the load current il:

4 + j3 = 480 * il*

il = (4 + j3) / 480

il = (4/480) + (j3/480)

il = 0.00833 + j0.00625

4) Finding the voltage drop across the transmission line:

The voltage drop across the transmission line can be calculated using Ohm's Law:

Vdrop = iTL * Zline

Vdrop = (26.67 - j20) * (0.18 + j0.24)

Vdrop = (26.67 * 0.18) + j(26.67 * 0.24) - j(20 * 0.18) - 0.24 * 20

Vdrop = 4.8006 + j5.3248

5) Finding the load voltage VL:

The load voltage can be calculated using the voltage transformation ratio:

VL/Vs = N2/N1 = 1/10

VL/480 = 1/10

VL = 480/10

VL = 48 V
