What will be the head rise
A Centrifugal pump can provide a 20-m head rise at 75 rev/min. If the rotation speed increases to 90 rev/min, what will be the head rise? Note the pump runs under dynamically similar conditions.

Nitrogen gas at steady-state-steady-flow undergoes a compression provess through a well-insulated compressor. The inlet pressure and temperature are 100 kPa and 300K THe exit pressure is 1500 kOa. The isentropic compressor efficiency, w_rev/w_actu
IF you can neglect the potential energy effects, the inlet velocity is 100 m/sec and the ratio of the outlet area to the inlet area is 4, WHAT is the power output of the turbine for a mass flow rate of 15 kg/sec?

Consider a house whose walls are 4 m high and 12 m long. Two of the walls of the house have no windows, while each of the other two walls has four wndows made of 0.6-cm-thick glass (k=0.78 W/m*C), 1.0 m x1.5 m in size.
Superheated ammonia enters an insulated nozzle at 200C and 800kPa. The flow through the low velocity inlet is at 0.015kg/s. At the discharge, the ammonia exits at 280kPa with a velocity of 400m/s.
A compressor receives air at 95kPa and 250C at low velocity. At the exit of the compressor, air discharges at 1.52MPa and 4300C with a velocity of 80m/s.
When boiling water, a hot plate takes an average of 464 seconds to boil 110 milliliters of water. Assume the temperature in the lab is 69 degrees fahrenheit. The hot plate is rated to provide 401 watts. How efficient is the hot plate? (Specific he
