Chapter 8, Problem 87P
A water tank tilled with solar-heated vater at 4OC is io he usen for showers in a field using gravity-driven flow. The system ijichides 35 in of 1.5-cm-diameter galvamzed non piping with four miter bends (9O) without vanes and a wide-opeii globe valve. If water is to flow at a raie of 1.2 Ls through the shower head. delennine how high the water level iii the tank must be from the exil level of the shower. Disiegaid the losses at the entrance and at the shower head, and neglect the effect of the kinetic energy correction factor.

In some high-rise buildings, water is stored in an elevatedtank on the roof to minimize pressure fluctuations inthe system. Consider water that is pumped through a 10-cmsteel pipe to the roof of a 200-m-tall building; the pump ison the ground floor. For a water temperature of lOOC and aflow of 0.02 m3/s, what is the pressure at the pump discharge(in kPa)?

- We are interested in pumping biodiesel between two pumping stations that are 300 km apart, being the second pumping station 300 m higher than the first one. We need a flow rate of 0.7 m/s using a 30 in i.d. commercial steel pipe. The pressure at the first station is 120 kPa and at the second stations it needs to be 350 kPa. Considering a kinematic viscosity for biodiesel of 4.09 x10 - 5 m²/s and a density of 874.6 kg/m?, determine the power required to pump the biodiesel from station 1 to station 2.
