A pump is being used to transport a liquid food product (p = 1250 kg/m³, µ = 1.5 cP) from a holding tank to a filling machine at mass flow rate of 2.5 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 open globe valve and three regular 90° flanged elbows in the system. The product is being pumped through a heat exchanger with 120 kPa of pressure drop due to friction before filling. Complete the process diagram and determine the actual power requirement if the efficiency of the pump and the motor are 85 % and 80%, respectively.

Water at 15°C is to be discharged from a reservoir at a rate of 18 L/s using two horizontal cast iron pipes connected in series and a pump between them. The first pipe is 5 m long and has a 6-cm diameter, while the second pipe is 5 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged, and losses associated with the connection of the pump are negligible. Neglecting the effect of the kinetic energy correction factor, determine the required pumping head and the minimum pumping power to maintain the indicated flow rate. (The density and dynamic viscosity of water at 15°C are ρ = 999.1 kg/m3 and μ = 1.138x10-3 kg/m.s. The loss coefficient is KL = 0.5 for a sharp-edged entrance.

I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?

The liquid storage tank shown in Fig has two inlet streams with mass flow rates w1 and w2 and an exit stream withflow rate w3. The cylindrical tank is 2.5 m tall and 2 m in diam-eter. The liquid has a density of 800 kg/m. Normal operating procedure is to fill the tank until the liquid level reaches a nom-inal value of 1.75 m using constant flow rates:w1=120 kg/min, w2=100 kg/min, and w3=200 kg/min. At that point, inlet low rate w1 is adjusted so that the level remains constant.However, on this particular day, corrosion of the tank has opened up a hole in the wall at a height of 1 m, producing a leak whose volumetric flow rate q4(m3/min) can be approximated by q4=0.025√h−1 where h is height in meters.(a)If the tank was initially empty, how long did it take for theliquid level to reach the corrosion point?(b)If mass flow rates w1,w2,and w3 are kept constant indefi-nitely, will the tank eventually overflow? Justify your answer.
