- In an annular section made of commercial steel pipe with an outer diameter or 13.78 inches inside a commercial steel pipe with an inner diameter of 23.62 inches carries a water flowrate of 600L/sec. The total length of the section is 10m. What is the frictional loss in meters of water at a temperature of 68o F?arrow_forwardA pelton type turbine was installed 31m below the head gate of the penstock. The head loss due to friction is 15% of the given elevation. The length of the penstock is 80m and the coefficient of friction is 0.00093. Determine the power output in MW.arrow_forwardThe 1/2 inch diameter hose can withstand a maximum pressure of 200 psi without breaking. Determine the maximum allowable length if the friction factor is 0.0022 and the flow rate is 0.010 cfs. Do not take into account minor losses.arrow_forward

- As seen in Figure 3 below, the water from the tank 1 is pumped to the tank 2 with a flow rate of 5,664 liters/s, passing through a pipe with a diameter of 50.8 mm and a length of 121.92 m. Some of the local losses in the system are also shown on the figure. Calculate the effective power of the pump by taking the relative roughness ɛ / d = 0.001 Note: For all questions, pwater = 1000 kg/m³, g=9.81m/s^2 , the kinematic viscosity of water is 1.0219x106 m²/s and the questions can be solved by accepting the values that are not given.arrow_forwardCompute the average speed of water in a pipe with a diameter of 5.0 cm and delivering 2.5 m3 of water per hour.
