µ A pump is being used to transport a liquid food product (p = 1000 kg/m³, μ = 1.5 cP) from a holding tank to a filling machine at a mass flow rate of 2 kg/s. The liquid level in the holding tank is 10 m above the pump, and the filling machine is 5 m above the pump. There is 100 m of 2-in nominal diameter sanitary pipeline between the holding tank and the filling machine, with one open globe valve and four regular 90° flanged elbows in the system. The product is being pumped through a heat exchanger with 100 kPa of pressure drop due to friction before filling. Determine the theoretical power requirement for the pump.

Question 7

dg A Consider the tank shown in (Figure 1), with water flowing in through pipe A and out through pipe B. The amount of water in the tank does not change with time, the diameter at A is da = 3.8 cm , the diameter at B is dB = 6.1 cm , and the average velocity at A is VA = 2.5 m/s , what is the average velocity at B? The density of water is pw = 1000 kg/m3 Express your answer in m/s to three significant figures. Now consider the same tank (Figure 1), with water flowing in through pipe A and out through pipe B. In this case, the amount of water in the tank is increasing at 0.8 kg/s Everything else is unchanged: the diameter at A is da = 3.8 cm , the diameter at B is de = 6.1 cm , and the average velocity at A is VA = 2.5 m/s, what is the average velocity at B? The density of water is Pw = 1000 kg/m³ Express your answer in m/s to three significant figures. В A Now consider a similar tank (Figure 2) full of air. Air flows in through pipe A and out through pipe B. The pressures and…
