The below figure shows a pump that transfers a steady stream of 35◦API crude oil from an oiltanker to a refinery storage tank, both free surfaces being open to the atmosphere. Theeffective length—including fittings—of the commercial steel pipe is 6,000 ft. The dischargeat point 4 is 200 ft above the pump exit, which is level with the free surface of oil in thetanker. However, because of an intervening hill, point 3 is at a higher altitude than point 4.Losses between points 1 and 2 may be ignored.The crude oil has the following properties:Density ρ = 53 lbm/ft 3 ; Viscosity μ = 13.2 cP; Vapour Pressure Pv = 4.0 psia Answer the following questions:1. If the combination of pump and motor is 80% efficient, how much electrical power(kW) is needed to drive the pump?2. If, in order to avoid vapour lock, the pressure in the pipeline must always be above thevapor pressure of the crude oil, what is the maximum permissible elevation of point 3relative to point 4?3. If the flow in the pipeline…

i just need final answer The water is delivered with piping system given in the figure below. The elevation difference between enteringsection and tank is 121,63 m. Estimate the gage pressure (MPa) at point 1. (Note: For water at 20°C, takep=998 kg/m and p=0.001 kg/ms.)
A piezometer and a Pitot tube are tapped into a horizontal water pipe, as shown in the Figure I belowto measure static and stagnation (static + dynamic) pressures. For the indicated water column heights,determine the velocity at the center of the pipe. Clearly state all asuumptions and illustrations
Find the friction for water at 60°C flowing at 0.0057 m³/s in a 4 in Sch 40 steel pipe.Answer to 3 decimal place
Consider a desired pump operating condition which adds 35 psi at a flow rate of 500 gpa to water. Ignore any changes in Kinetic or potential energy and assume isothermal flow (ie. Internal energy is constant, this is normal assumption we make when analyzing fluid flows in piping systems). Apply the energy balance only across the pump starting with full energy balance and simplifying to solve for the pump head symbolically. Then begin careful of unit, solve for pump head in feet. Given erosion 500 gpm P=62 lbs/ft^3 A- 10.5 ft B- 100.8 ft C- 50.1 ft D-80.7 ft
Air velocity in a duct is measured as 38.2 m/s by a pitot tube. Density of flowing air 1.3 kg/m3. If the pressure difference recorded by the pitot static tube is 0.1 m of water, calculate the coefficient of velocity of the pitot static tube. A Figure or Free Body Diagram will be much appreciated. Thank you
