What is the horsepower required by the pump? A Keystone Pipeline has a diameter of 36 inches and a design flow rate of 590,000 barrels per day of crude oil at 40°C. Estimate thepump horsepower required if the length of the pipe is 1.5 mile(s). The pipe material is new steel. For crude oil at 40°C, take μ= 0.0053kg/m-s÷ 47.88 = 0.0000111 slug/ft-s. The density, with SG = 0.86, is 0.86(1.94) = 1.67 slug/ft³. Take f≈ 0.0155.

A Keystone Pipeline has a diameter of 36 inches and a design flow rate of 590,000 barrels per day of crude oil at 40ºC. Estimate the pump horsepower required if the length of the pipe is 2.9 mile(s). The pipe material is new steel. For crude oil at 40ºC, take μ ≈ 0.0053 kg/m-s ÷ 47.88 = 0.0000111 slug/ft-s. The density, with SG = 0.86, is 0.86(1.94) = 1.67 slug/ft3. Take f ≈ 0.0155. Answer is in hp. Last answer was wrong! please help!
(2) It is desired to deliver 60 m'/hr of water at 20°C through horizontal asphalted cast iron pipe. Estimate the pipe diameter d that will cause the pressure drop to be exactly 40 kPa per 100 m of pipe length. Take water density p Solve this problem iteratively using either Moody chart or the Colebrook equation. 998 kg/m and dynamic viscosity µ = 0.001 kg/(m.s).
The ethanol solution is pumped into a vessel 25 m above the reference point through a 25 mm diameter steel pipe at a rate of 8 m3/hour. The length of the pipe is 35m and there are 2 elbows. Calculate the pump power requirement. The properties of the solution are density 975 kg/m3 and viscosity 4x 10-4 Pa s. a. Reynolds number = b. Energy Loss along a straight pipe = J/kg. c. Energy Loss in turns = J/kg. d. Total energy to overcome friction = J/kg. e. Energy to raise water to height = J/kg. f. Theoretical energy requirement of the pump kg ethanol/second = J/kg. g. Actual pump power requirement = watt.
Find the pressure at point 2 given the isometric drawing of the commercial steel pipeline indicating the straight pipes length and with the following data below:Loss coefficients:• check valve, k = 5.0• gate valves, k = 0.20• elbows, k = 0.75• flowmeter, k = 13.0Pump flowrate = 10 m3/hrFluid power adding by pump = 3.7 HPPressure at point 1 = 60 kPagPipe inside diameter = 50mmViscosity = 0.17 Pa.sSpecific gravity = 0.89Pipe inside surface roughness = 0.00015 ft.
Required information Assume that ri = 0.149 m, ro = 0.15 m, µ = 1.49 kg/m-s (glycerin), p = 1260 kg/m3, and Oj = 120 rev/min = 12.57 rad/s with the inner cylinder rotating and outer cylinder fixed. Calculate the inner shear stress for the given flow. The inner shear stress is Pa.

What is the volume flow rate for water (viscosity= .0010 Pa×s) through a length of pipe L= 0.60m and pipe radius r= 1.03cm if the pressure difference across this length of pipe is 5.2 kPa? Note that 1 kPa= 1000 Pa. What would the volume flow rate be if the same pipe had a radius that is reduced by 21% (i.e. the radius is 79% of its previous value)? Let's call this flow rate Q1. What is the ratio of Q1 to the original flow rate Q? Express this as a decimal number.

answer (a) and (b)
It is desired to pass water from point 1 to point 3 to run a fluid engine, pressure p1= 700kpa and pressure p3=500kpa, the pipe diameter is uniform. The external diameter has a value of 28mm with a thickness of 2mm. The fluid velocity in the pipe is 3 m/s. If the friction losses due to the elbow and the valve are estimated to be 4N.m/N, what is the power in kW it should have at the output if it has an efficiency of 85 %?
Assume the following standard values if not provided with the problem statement • Air o p = 1.2 kg/m³ μ = 1.8 x 10-5 kg/(m s) • Water o p = 1000 kg/m³ o μ = 0.001 kg/(m s)
