Chapter 5, Problem 5.20P

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! show all steps please thanks

40. Water flows through a pipe of varying cross-section and varying elevation at the rate of 22.2m3/min. At one section of the pipe 3 m from the ground, the radius of the pipe is 36 cm and the pressure is 12 N/cm^2.What is the pressure at a section where the radius of the pipe is 18cm and is 0.7 m from the ground level?A. 136 123 N/m2 B. 50 N/cm2 C. 750 000 N/m2 D. 12 N/cm2

Water vapor with a pressure of 160 bar and a temperature of 480°C enters a stable turbine with a volumetric flow of 800 m3/min. About 18% of the incoming mass flow exits a part of the turbine at a pressure of 5 bar, a temperature of 240°C and a velocity of 25 m/s. The rest comes out from another part of the turbine with a pressure of 0.06 bar, a quality of 94% and a speed of 400 m/s. Determine the diameters of each outlet channel in m.

Two gaseous streams containing the same fluid enter a mixing chamber and leave as a single stream. For the first gas, the entrance conditions are Ai 500 cm2, vi 130 m/s, pi 1.60 kg/m3. For the second gas, the entrance conditions are A2 400 cm2, 7h2 8.84 kg/s, u2 z0.502 m3/kg. The exit stream condition is v3 130 m/s and v3 0.437 m3/kg. Determine (a)the total mass leaving
