You have been asked to design a similar pump from the
existing one. The existing pump works for water is of impeller
diameter equals 6 cm and its performance data is shown here when
working at 1725 rpm. The newly design pump is for a refrigerant
(R-134A) and it must produce 450 cm of head at 1600 rpm when
working at its best efficiency. One of your colleagues did
preliminary analysis and develop the performance curves in
dimensionless form for...

While taking a shower, you notice that the shower head is made up of 42 small round openings, each with a radius of 2.00 mm. You also determine that it takes 5.00 s for the shower to completely fill a 1.00-liter container you hold in the water stream. The water for the shower is pumped by pump that is 5 10 m below the eve of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g...

The pump-turbine system in Figure 4 draws the water from the
upper reservoir in the daytime to produce power for a city. At
night, it pumps water from lower to upper reservoir to restore the
situation. For the design flow rate of 0.157m3/s, the
friction head loss,
hL=4vA2/(2g).
Determine the jet velocity at A.
Find the friction head loss in the system.
Estimate the energy head in meters delivered by the pump at
night.

A vapor-compression heat pump system uses Refrigerant R-134a as the working fluid. The refrigerant enters the compressor at 2.0bar, -5degC and with a mass-flow rate of 26g/s. Compression is adiabatic to 11.6bar, 60degC and the refrigerant exits the condenser 8degC sub-cooled. a) Draw a P-h chart to visualise the refrigeration cycle and display known data. b) Determine the power input to the compressor in kW c) Determine the heating capacity of the system in kW d) Determine the coefficient of...
