thermo fluid | Engineering homework help

 ‘m working on a engineering multi-part question and need support to help me understand better.Water (density of 998.2 kg/m3 and a viscosity of 0.001002 Pa s) flows through a piping system into an open reservoir, as shown in the diagram. The internal diameter of the pipe is 5 cm. If the gauge pressure at point 1 is 75 kPa, calculate the elevation difference between the inlet and free surface in the reservoir for which a flow rate of 36 m3/h can …….
