Question
- Water is being pumped the through one inch diameter piping arrangement to a higher elevation (5 meters up). Assume incompressible fluid conditions and some heat losses to the surroundings. At the inlet water pressure is 1 bar, temperature 15C, and volumetric flow rate is 0.02 m3/s. At the exit pressure is 2.2 bar, temperature is 10C and velocity of the stream is 40 m/s.
Determine:
a.Density of the inlet stream using NIST tables.
b.Mass flow rate [kg/s]
c.Determine h2 from known p2 and T2 using NIST tables
d.Find heat rate removed from Q=m(h1-h2)
- Use Energy Balance Equation with enthalpy difference and in the units of kW to find pumping power in kW. NOTE: The heat is removed from the system, so it should be negative in your equation!

The question was, standard hydraulic oil is flowing at 10gpm and 10psi at the pump outlet. The system then flows uphill to an elevation of 100ft. What is the pressure at this point?arrow_forwardConsider water flowing through a water hose of length of 100 ft, diameter of 3/8 inch, and average surface roughness 5-105 ft. The gage pressure at the hose inlet is 40 psi. The hose contains a ball valve which controls the flow rate. Calculate the mass flow rate of water through the hose with the ball valve completely open and with ball valve 2/3 closed. Hint: Determining the friction factor requires an iterative approach - start the iterations by assuming that the friction factor is equal to 0.01 and perform at least 3 iterations.arrow_forward
- Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank. Please calculate the velocity of leakage water that discharges to the normal atmosphere. The dimension of the tank is 20-meter in height and 10-meter in diameter. The gauge pressure of the water tank top is 0.1M Pa.
