Please correct the answers for the attached part with step-by-step calculations: Given information below: Water flows at a rate of 2.4f * t ^ 3 / s in an old, rusty 7.8-in.-diameter pipe that has a relative roughness of 0.010. It is proposed that by inserting a smooth plastic liner with an inside diameter of 7.0 in. into the old pipe as shown in the Figure the pressure drop per mile can be reduced. Is it true that the lined pipe can carry the required 2.4f * t ^ 3 / s at a lower pressure drop than in the old pipe? Support your answer with appropriate calculations.Attached Part that needs correcting.
A 500 mm diameter pipe gradually reduces to 20 mm diameter and the gradually enlarge to its original size. Given the pressure at the base of the convergence of 0.60 MPa with a flow of 0.08 cu. m/s, 1. What is the velocity at point 1? 2. What is the velocity head at point 2? 3. Neglecting the head loss, the pressure of the smallest section is?
A farmer is to pump water at 70°F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90° smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a flow rate of 1.5 ft3/s and an overall pump efficiency of 70 percent, determine the required electric power input to the pump.
Flow In Closed Conduits 2. Water at 25C flows through a 200-mm diameter new cast iron pipe at a velocity of 2 m/s if the pipe is 720 m long, determine the head lost due to friction using Darcy – Weisbach formula. Answer: _______________________________
Water at 59 F flows through a straight section of a 6-in-ID cast-iron pipe with an average velocity of 4 fps. The pipe is 120 ft long, and there is an increase in elevation of 2 ft from the inlet of the pipe to its exit. Find the power required to produce this flow rate for the specified conditions. solve for the head loss only
Water flow at a 250mm diameter horizontal pipe 90m long. The friction factor is 0.023. If the pressure at the starting point is 80KPa and the pressure at the end point is 50KPa. Determine the discharge at the pipe.
Water (ρ=998 kg/m³, μ=1.02x10^-3 kg/ms) flows through a 598 m length of pipe with 150 mm in diameter at 60 L/s. Determine the pipe roughness, ɛ if the head loss is 49 m.
A long 0.3 m pipeline laid between two reservoirs carries a flowrate of 0.14 m3/s ofwater. A parallel pipe of the same friction factor is laid beside this one. Calculate the approximatediameter of the second pipe if it is to carry 0.28 m3/s
Water at 25℃ flows from a large reservoir to a smaller one through two clean cast iron pipes in series. A pipeline carrying 280 kg/s is 500 m long, suddenly enlarges from 300 mm to 450 mm for the remaining 600 m. If the exit and entry of the reservoirs to the pipes are both sharp-edged, determine the elevation difference between the reservoirs. Take kinetic energy correction factors as 1 and consider all losses
A 250 mm diameter and 3 km long straight pipe connects two reservoirs of water surface elevations 135.00 m and 60.00 m. A 1.5 km long, 300 mm diameter pipe is laid parallel to 250 mm diameter pipe from its mid-point to the lower reservoir. Neglecting minor losses and assuming friction factor as 0.02 for both the pipes. Find the original discharge and the increased discharge
Consider flow from a water reservoir through a circular hole of diameter D at the side wall at a vertical distance H from the free surface. The flow rate through an actual hole with a slightly rounded entrance (KL = 0.12). is considerably less than the flow rate calculated assuming “frictionless” flow and thus zero loss for the hole. Disregarding the effect of the kinetic energy correction factor, obtain a relation for the “equivalent diameter” of the sharp-edged hole for use in frictionless flow relations.
Water at 20°C is pumped through a smooth 12-cm-diameter pipe 10 kmlong, at a flow rate of 75 m3/h. The inlet is fed by a pump at an absolute pressure of 4 MPa.The exit is at standard atmospheric pressure (101 kPa) and is 200 m higher. Calculate the frictional head loss Hf and compare it to the velocity head of the flow.
