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!

A tanker carrying tolueneis unloaded to an onshore storage tank using the ship’s pumps. The pipeline is 225-mm inside diameter and 900-m long (200-m long suction line, 700-m long discharged line). Miscellaneous losses due to fittings, valves, etc., amount to 100 equivalent pipe diameters at the suction side, and 500 equivalent pipe diameters at the discharged side. The maximum liquid level in the destination storage tank is 30 m above the lowest liquid level in the ship’s tanks. The ship’s tanks are nitrogen blanketed and maintained at an absolute pressure of 1.05 bar (1 bar = 10^5 Pa). The storage tank has a floating roof, which exerts an absolute pressure of 1.1 bar on the liquid. The ship must unload 1000 metric tons within 5 hours. Taking pump efficiency as 70%, (ρ = 874 kg/m3, μ = 0.62 cP, Pvapor = 0.037 atm absolute). Determine: Discharge head (m) and pressure (Pa) Actual pump power (kW) Available NPSH (m)

Suppose that you are willing to determine the diameter of the water jet impinging to the sink from the kitchen tap.The tap is produced to supply three different flow rates of the low, medium, and high. For each flow rate level, waterthat comes from the tap fills the beaker with a volume of 30 mL in 10 s, 6 s, and 2 s, respectively. The outlet of the tapis 13 mm, and the distance between the tap outlet and the sink is 53 mm. Determine the diameters of the water jetimpinging on the sink at three given flow rates.
