A turbine operating under steady flow conditions receives steam at the
following state : pressure 13.8 bar ; specific volume 0.143 m3/kg ;
internal energy 2590 kJ/kg ; velocity 30 m/s. The state of the steam
leaving the turbine is : pressure 0.35 bar ; specific volume 4.37 m3/kg
; internal energy 2360
kJ/kg ; velocity 90 m/s. Heat is lost to the surroundings at the rate of
0.25 kJ/s. If the rate of steam flow is 0.38 kg/s, what is the power
developed by the turbine ?

How many moles of h2so4 are present in 1.63 liters of a 0.954 M solution
15 kg of air per minute is delivered by a centrifugal compressor. The
inlet and outlet conditions of air are :
C1 = 10 m/s, p1 = 1 bar, v1 = 0.5 m3/kg and C2 = 80 m/s, p2 = 7 bar,
v2 = 0.15 m3/kg. The increase in enthalpy of air passing through the
compressor is 160 kJ/kg, and heat loss to the surroundings is 720
kJ/min.
Assuming that inlet and discharge lines are at the same level, find :
(i) Motor power required to drive the compressor.
(ii) Ratio of inlet to outlet pipe diameter.
