Answer:
a)
The crack and connecting rod is used in the design of car.This mechanism is known as slider -crank mechanism.
Components:
1.Inlet tube
2. Wheel
3. Exhaust
4. Engine
5.Air tank
6.Pressure gauge
7.Stand
8. Gate valve
b)
The efficiency of air engine is less as compare to efficiency of electric engine and this is not ecofriendly because it produce green house gases.These gases affect the environment.
c)
it can run around 722 km when it is full charge.
Answer:
Generated analytical expression is:
y = C / [0.656*(4.35 + 0.656x)] - 1.859
C is constant.
Explanation:
Steps to generate an analytical expression for the flow streamlines and draw several streamlines in the upper-right quadrant from x = 0 to 5 and y=0 to 6. the following steps are listed.
Step 1: Write the velocity field.
Step 2: Write the 'x' and 'y' component of the velocity field for two dimensional study flow.
Step 3: Write the streamline function.
Step 4: Integrate to obtain the streamline's equation.
Step 5: Plot the streamline field.

Answer:
The process is not possible.
Explanation:
We know for ideal condition, the work done for isothermal process is
=
and for ideal gas, we know PV = mRT
Therefore, = mRT
= mRT
= 0.287 x 400
= -126.12 kJ/kg (negative sign indicates that the process is compressive, so work input to the compressor is 126.12 kJ/kg )
Now we know for adiabatic compression process
P = C
We know
= 556 K
For adiabatic work done, =
=
=
= -99.49 kJ/kg (negative sign indicates that the process is compressive, so work input to the compressor is 99.49 kJ/kg )
We know that in isothermal process, work input to the compressor is minimum. But in the above adiabatic polytropic process, work input to the compressor is less than the work done in the isothermal process.
Thus the process is not possible.
Answer:
Latitude = 76.33 degrees. Maximum Separation = 41,127.21Km
Explanation:
Parameters used:
1. Smax = Geo stationery satellite position with maximum slant range to the earth station
2. Smin = Geo stationery satellite position with minimum slant range to the earth
3. E = Earth station
4. C = Centre of the earth
5. Re= Radius of the earth = 6738.14km
6. Rs = Orbit radius of the satellite = 42164.17km
For a minimum elevation of 5°
CSmax/Sin 95° = CE/Sinξ
Therefore, Sin ξ = 6738.14Sin 95° /42164.17
ξ=8.667
ψ=180-95-8.667=76.33° latitude
Applying the sin law;
ESmax/Sinψ = CSmax/Sin95
Therefore; ESmax = CSmax(Sin76.33)/Sin95
ESmax = 42164.17*0.9717/0.9962
ESmax=41127.21Km
