Answer:
Explanation:
Calculating the exit temperature for K = 1.4
The value of is determined via the expression:
where ;
R = universal gas constant =
k = constant = 1.4
The derived expression from mass and energy rate balances reduce for the isothermal process of ideal gas is :
------ equation(1)
we can rewrite the above equation as :
where:
Thus, the exit temperature = 402.36 K
The exit pressure is determined by using the relation:
Therefore, the exit pressure is 17.79 bar
Answer:
Explanation:
Given
time taken
Speed acquired in 2 sec
Here initial velocity is zero
acceleration is the rate of change of velocity in a given time
Distance travel in this time
where
s=displacement
u=initial velocity
a=acceleration
t=time
so Jet Plane travels a distance of 42 m in 2 s
