Answer:
Option B Lower than
Explanation:
Gauge pressure is a relative measurement based on atmospheric pressure. Gauge pressure can be positive if it is above atmospheric pressure or it can also be negative it is below. On another hand, absolute pressure is an actual pressure in a space and its value has always to be zero or above. Basically absolute pressure is zero if it is in a perfect vacuum. So the measurement of absolute pressure is gauge pressure + atmospheric pressure. This is the reason in normal condition the gauge pressure = absolute pressure - atmospheric pressure and therefore is lower than absolute pressure
Answer:
b) Determine the heat transfer into the cycle and the net work for the cycle, in kJ.
Explanation:
Answer:
a)27.9%
b)
Explanation:
Given that
Fuel energy content = 73.1 MJ/kg
Useful power = 17.4 KW
Heat rejection rate = 44.8 KW
From first law of thermodynamics
Heat addition rate =Heat rejection rate + Power out put
Now by putting the values in the above formula
Heat addition rate = 44.8 + 17.4
Heat addition rate =62.2 KW
We know that efficiency is given as follows
So
So the efficiency is 27.9%.
Now to find usage rate of fuel
Lets take usage rate is 
Fuel energy content x usage rate of fuel = Heat addition rate
Now by putting the values
