Question
Water flows at a rate of 28 L/s through a horizontal pipe whose diameter is constant at 3 cm. The pressure drop across a valve in the
pipe is measured to be 2 kPa, as shown in the given figure. Determine the irreversible head loss of the valve and the useful pumping
power needed to overcome the resulting pressure drop. Take the density of water to be p-1000 kg/m³
