Answer:
W=-940.36 KJ
Explanation:
Given that
Process follows pv=constant
So this is the isothermal process and work in isothermal process given as
Now by putting the values (1.4 bar =140 KPa)
W=-940.36 KJ
Negative sign indicates that this is a compression process and work will given to the system.
Answer:
b)1.08 N
Explanation:
Given that
velocity of air V= 45 m/s
Diameter of pipe = 2 cm
Force exerted by fluid F
So force exerted in x-direction
F=0.763 N
So force exerted in y-direction
F=0.763 N
So the resultant force R
R=1.079
So the force required to hold the pipe is 1.08 N.
