PROBLEM 1: Seventy kilojoules of work is done by each kilogram of fluid passing through an apparatus under steady-flow conditions. In the inlet pipe, which is located 30 m above the floor, the specific volume is 3 m³/kg, the pressure is 300 kPa, and the velocity is 50 m/s. In the discharge pipe, which is 15 m below the floor, the specific volume is 9 m³/kg, the pressure is 60 kPa, and the velocity is 150 m/s. Heat loss from the fluid is 3 kJ/kg. Determine the change in internal energy of the fluid passing through the apparatus.

Please show sholutios completely use those formula that i give. thank youuu....

Please answer it in 2hrs.

This is the most frequently used form because many steady-flow systems have only one inlet and
one exit.

Q-ΔΡE+ΔΚΕ + ΔΗ + W
For a Unit Mass
(9-5)
q=g(z, -z,)+ (v-v.?)+(h, -h, ) + w

change in internal energy of the fluid passing through the apparatus.
Ans: 277.4 kJ/kg
