Part A Head loss A gate valve is being used as a shut-off valve in a pipe system. When the valve is fully open, the flow through the 8-cm diameter pipe is 50 L/min. What is the head loss at the gate valve? One liter is 0.001 cubic meters. Express your answer in m to three significant figures.

If the flow rate is Q=0.04 m/s, what is the pressure drop due to expansion? The specific weight of water is yw 9.802 kN/m Express your answer in kPa to three significant figures.
