A pump generates high pressure water as indicated in fig 3. The Inlet pressure and outlet pressure are 110 and 300 kPa respectively. The mass flow rate is 3 kg/sec. The inlet pipe is 1 inch diameter and outlet pipe is 0.5 inch. Neglect elevation difference and internal energy changes across inlet and outlet. a) Culculate velocity İf water at inlet and outlet(5) b) Choose a suitable control volume, and write down and expression for conservation of energy applicable to...

A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree C through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet temperature is raised to 40 degree C?

A Venturi tube may be used as a fluid flow meter. If the fluid flow rate in m3/s is 1.6 * 10-3 and the radius R1 = 2.4 *10-2 m of the inlet tube is 2.9 times the radius R2 of the outlet tube, and the fluid is water (ρ = 1000 kg/m3), find the pressure difference P1 - P2 in units of kPa. Enter a number with one digit behind the decimal point.
