Answer:
b.) pneumatic system
Explanation:
This system uses compressed air to transmit and control energy
Answer:
A pneumatic system is a system that uses compressed air to transmit and control energy. ... Most pneumatic systems rely on a constant supply of compressed air to make them work. This is provided by an air compressor. The compressor sucks in air from the atmosphere and stores it in a high pressure tank called a receiver.

Answer:
Power in kW is 104 kW
Power in horsepower is 139.41 hp
Solution:
As per the question:
Velocity of the airplane,
Force exerted by the propeller,
Now,
The useful power that the propeller delivered, :
Here, work done provides the useful energy
Also, Work done is the product of the displacement, 'x' of an object when acted upon by some external force.
Thus
Now, putting given values in it:
In horsepower:
1 hp = 746 W
Thus
(a) The thermal efficiency of the cycle.
The thermal efficiency of the cycle is given by
NThermal= net work/ heat supplied
NThermal= WNet/QH
=2026.08/4547.82= 44.55%
(b) The backwork ratio:
compressor work/ turbine work
=1760.76/3786.84= 0.465
(c) The net power developed:
WNet= WT-WC
WNet= 3786.84- 1760.76= 2026.08 kW
