water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kw of useful mechanical power to that water. the free surface of upper reservoir is 45 m higher than the surface of the lower reservoir. if the flow rate of water is measured to be 0.03 m3/s, determine the irreversible head loss of the system.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
