Water at 20°c flows through a pump impeller. the inner and outer diameters of the impeller are 160 mm and 400 mm, and the width of the pump blades is 55 mm. the pump operates at 1750 rpm with inner blade angle of 70° and outer blade angle of 60°.

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.
