You are withdrawing water from a lake to fill a water tank. The water tank is 50 m above the water surface of the lake. The total length of pipe from the lake to the tank is 2500 m. A hydraulic engineer has told you that the frictional losses in the pipe are 0.01 m of head per meter of pipe at the desired flowrate, so what is the head of the pump that is needed

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
