Water is pumped between two large open reservoirs through 1.5 km of smooth pipe. The surfaces in the two reservoirs are at the same elevation. When the pump adds 20kW to the water, the flowrate is 1 m3/s. If minor losses are negligible. Determine the pipe diameter.

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

How much power could a wind turbine produce if it had the following specifications? cp = 0.45 -d=1.2kg/m3 d=50m v 5m/s

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
