- In the diesel oil transfer facility (ρ rel = 0.85), from the storage tank to the consumption tank, we want to install a pump to circulate a flow of 45 lt / s. The 400m long pipe is cast 150mm in diameter and consists of a check valve, a gate valve and 2 commercial medium radius elbows. The consumption tank is pressurized to 3.8 bar of manometric pressure. Determine the drive power of the pump in kW if its performance is 68%. Additional data, load loss factors: 1. Check valve Kr = 1.5 2. Gate valve open Kv = 0.21 3.

- Water at 20°C flows in a 100-mm-diameter new cast iron pipe with a velocity of 5.0 m/s. Determine thepressure drop in kPa per 100 m of pipe and the power lost (in kilowatts) to friction.Ans. 314 kPa per 100 m, 12.36 kW per 100 m [Note: Indicate the formula used in determining the friction factor. (Colebrook Equation, Haaland Equation, andor Swamee Jain Equation). If not given, Use properties of fluid based on temperature available on the internet. E.g. (density, viscosity) . Apply roughness of pipe values from https://www.pipeflow.com/pipe-pressure-drop-calculations/pipe-roughness}Engine oil at 20 C flows in a 13-cm-diameter pipe at a rate of 900 L/min. The friction factor for this flow is?In a geothermal district heating system, 10,000 kg/sof hot water must be delivered a distance of 10 km in ahorizontal pipe. The minor losses are negligible, and the onlysignificant energy loss arises from pipe friction. The frictionfactor is taken to be 0.015. Specifying a larger-diameter pipewould reduce water velocity, velocity head, pipe friction, andthus power consumption. But a larger pipe would also costmore money initially to purchase and install. Otherwise stated,there is an optimum pipe diameter that will minimize the sumof pipe cost and future electric power cost.Assume the system will run 24 h/day, every day, for 30 years.During this time the cost of electricity remains constant at$0.06/kWh. Assume system performance stays constant overthe decades (this may not be true, especially if highly mineralizedwater is passed through the pipeline—scale may form).The pump has an overall efficiency of 80 percent. The cost topurchase, install, and insulate a 10-km pipe depends on…
- Water (kinematic viscosity, ν, = 1.14 *10-6 m2/s) flows through a piping system with a flow rate of 0.75 m3/s. The pipe is 2600 m long and 600 mm inside diameter. The pipe has four gate valves,two angle valves, one swing check valve, three standard tees through flow, and three 90o standardelbows. Calculate the following:a- The total length of the piping system.b- The Darcy friction factor if the pipe is fully smooth.Find Reynolds number for 100% Glycerol at 75°C flowing through a 2.5" Sch 80 pipe at 10 lbm/sWater at 16,2°C is to be discharged from a reservoir at a rate of 16,2 L/s using two horizontal cast iron (roughness value ɛ=0.00026m) pipes connected in series and a pump between them. The first pipe is 26,2 m long and has a 66,2 mm diameter, while the second pipe is 36,2 m long and has a 46,2 mm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged (KL=0.562), 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, the minimum pumping power and electric motor power for total efficiency value of 76,2% to maintain the indicated flow rate. Water density is r=996,2 kg/m3, dynamic viscosity µ= 1.162x10-3kg/ms. Solve the problem by making the necessary assumptions and drawing the schematic figure.
