QI: A- 0.5kg/s of a fluid flows in a steady state process. The properties of fluid at entrance are measured as pl = 1.4bar, density 2.5kg/m3, ul 920kJ/kg while at exit the properties are p2 = 5.6 bar, density = 5 kg/m3 , u2 720KJ/kg. The velocity at entrance is 200 m/sec, while at exit it is 180m/sec. It rejects 60kw of heat and rises through 60m during the flow. Find the change of enthalpy and the rate of work done.

Question

Ql: A- 0.5kg/s of a fluid flows in a steady state process. The properties of fluid at entrance are
measured as pl = 1.4bar, density = 2.5kg/m3 , ul = 920kJ/kg while at exit the properties are p2 = 5.6
bar, density = 5 kg/m3 , u2 = 720KJ/kg. The velocity at entrance is 200 m/sec, while at exit it is
180m/sec. It rejects 60kw of heat and rises through 60m during the flow. Find the change of enthalpy
and the rate of work done.
