In a process plant, water is flowing through a globe valve. The pressure before the entering the globe valve is 10 bar
and the velocity through a 100 mm valve inlet is 4 m/s. The valve is horizontally placed and when it is 50% open the
downstream pressure is observed to be 2 bar. The outlet section of the valve has same diameter as the inlet section.
Calculate the power needed to for water to flow through this valve.
4.28 kW
8.28 kW
10.28 kW
None of the above
O 6.28 kW
Find an expression for the rate of change of the mass of water in the tank.
Q2: A nozzle is a device for increasing the velocity of steadily flowing stream of fluid. At the
inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the
exit from nozzle the enthalpy is 2790 kJ/kg. The nozzle is vertical with a 0.5 m height; ignore
the heat loss from it. Find the velocity at the nozzle exit and the rate of flow of fluid if the inlet
area is 0.1 m² and the specific volume at inlet is 0.19 m³/kg.
