Answer:
0.8 kilograms of fuel are consumed each second.
Explanation:
As turbines are steady-state devices, the thermal efficiency of a turbine is equal to the percentage of the ratio of the output power to fluid power, that is:
The fluid power is:
Which means that gas turbine consumes 40 megajoules of fluid energy each second, which is heated and pressurized with help of the fuel, whose amount of consumption per second is:
0.8 kilograms of fuel are consumed each second.
Answer:

Explanation:
Hi!
To solve this problem follow the steps below, the procedure is attached in an image
1. Draw the complete outline of the problem.
2.to find the heat Raise the heat transfer equation for cylinders from the inside of the metal tube, to the outside of the insulation.
3. Once the heat is found, Pose the heat transfer equation for cylinders from the inner part of the metal tube to the outside of the metal tube and solve to find the temperature
Answer:
Number of trucks required = 203
Explanation:
Calculate the amount of soil need to be excavated from the borrow site by using the following equation:
VF = Vf + (◇V/◇Vf) × Vf
Here, ◇V is change in volume during grading, Vf is the Volume of fill, and ◇V/◇Vf is the bulkage factor
Substitute in the equation.
VF = 50000 + (30/100) 50000
VF = 50000 + 15000
VF = 65000yd^3
Number of trucks needed = (Truck cycle time / Excavator time ) × VF
Number of truck heeded= (15 / (16× 5 ×60) × 65000
Number of trucks = 975000/ 4800
Number of trucks = 203
