- Water discharge flow rate of 0.001 m3/s is delivered through the 30 mm cast iron pipe? €=0.15 Calculate the total losses in the pipe For minor losses, take K for the Entrance: 0.3 Exit: 0.5 Valve 1.8 the pipe Length L_687 marrow_forwardWater flows through the galvanized iron pipe system whose diameter is 0.75 inches and flow rate is 0.020 cfs. Do you agree with the fact that friction losses in the straight parts of the piping system are negligible with respect to losses to fittings?arrow_forwardTwo pressurized prismatic tanks A and B are connected at their sides by an orifice 140 mm in diameter. Tank A contains water at a depth of 3 m above the orifice and a pressure of 50 kPa on the water surface. Tank B also contains water at a depth of 2 m above the orifice and a pressure of 15kPa on the water surface. The coefficient of discharge is 0.86 and the coefficient of velocity is 0.92.

- A centrifugal pump is used to supply a highly viscous fluid to a chemical plant. The chemicalplant is located at a height of 20 m from the pumping station level. The flow rate required tobe pumped is 0.005 m3 /s. The pipe diameter used for pumping is 30 cm and the total length ofthe pipeline is 50 m. The pipe exits to atmospheric conditions. Compute the Reynolds numberand determine whether the flow is laminar or turbulent. Determine the pressure that should bedelivered by the pump at its exit in order to maintain the flow. Also compute the power inputfor the pump assuming a pump efficiency of 100 %. Take the viscosity of the fluid to be0.01Pa.s. Take the density of the fluid to be 1500 Kg/m3 .arrow_forwardA horizontal pipe, originally smooth but due to constant use, was found to be scaling through corrosion where the effective surface roughness rises. This resulted for the fanning friction factor to be twice the original value. Determine the percent increase in the pipe diameter if the volumetric flowrate and pressure difference remains the same when it was new and old. Blank 1 %arrow_forwardWater 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.arrow_forward
- Assumptions of a discharge and a friction head loss through the series of pipe and the parallel of pipe are different. For pipes in series, the total discharge equals to the individual discharge in each pipe. For pipes in parallel, the total friction head loss equals to the individual friction head loss in each pipe. True or falsearrow_forwardA 230-m-long pipeline delivers 20◦C water to a storage reservoir located downstream. The pipeline is galva-nized with an average roughness height of 0.2 mm. An axial pump is used to pressurize upstream water. Thewater surface in the reservoir is located 18 m above the centerline of the pump. The pump discharges waterat an absolute pressure of 400 kPa and a volume flow rate of 50 L/s. Calculate a diameter of pipe requiredto achieve such an operating condition. If needed, use the Moody diagram on the last page, or one can solvethe Colebrook equation using, for example, Matlab.arrow_forward04: Three pipes of diameters 300 mm, 200 mm and 400 mm and lengths 450 m, 255 m and 315 m, respectively, are connected in series. The difference in water surface levels in two tanks is 18 m. Determine the rate of water flow if coefficients of friction are 0.0075, 0.0078 and 0.0072, respectively, considering: (a) with minor losses, (b) without (neglecting) ‘minor losses.arrow_forward

The throat diameter of the me- ter is 100 mm and the pressure at the throat is 400 mm of mercury below atmosphere. If 3% of the differential pressure is lost between inlet and the throat, determine the flow rate of the pipeline. PLEASE USE BERNOULLI'S ENERGY EQUATION. INCLUDE COMPLETE SOLUTIONarrow_forwardPlease 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?
