Problem If the flow of 0.10 m³/s of water is to be maintained in the system shown, what power must be added to the water by the pump? The pipe is made of forged steel and is 15 cm in diameter. Neglect all the component head losses and consider only the major head loss for this problem. Assume that α₁ = α₂ = 1. Temperature is 15°C. Water Elevation 10 m T = 10°C 40 m Elevation 13 m + 40 m

Three pipes of 400 mm, 350 mm and 300 mm diameter are connected in series between two reservoirs with a difference in level of 12 m. The friction factors are 0.024, 0.021 and 0.019 respectively. The lengths are 200 m, 300 m and 250 m respectively. Which of the following statements is TRUE.  *The discharge in pipe 1, 2 and 3 are equal.*The head loss in pipes 1, 2 and 3 are equal.*The total head loss is negligible.*The largest pipe will have the largest head loss The flow in m^3/s in PIPE 3 is nearest to... *0.04*0.2*0.3*0.1 What is the head loss in meters in pipe 3? *6.474 m*15.458 m*2.785 m*7.755 m Determine the length of an equivalent 350mm diameter pipe.  *906.123 m*1545.812 m*417.236 m*402.582 m   Please answer with complete and detailed solutions. thank you.

Consider the section of water distribution piping shown below. Ignoring minor losses, find the flow rate in pipe CB, the total energy at point C, and the pressure at point D. The water temperature is 10°C. C-D: 400m @ 325mm ø D-B: 400m @ 325mm (C=140,k, =1.5x106 m) (C=140,k=1.5x10“ m) Demand = 0.78m³/s C D ZD= 50m Ев 80m zc=45m ZB= 40m A-B: 3000m @ 400mm ở E = 141m (C=120, k =5.3x10+ m) ZA = 60m Flow rate in pipe CB (in m3/s)? Total energy at C (in m)? Pressure at D (kPa)? A-C: 2200m @500mm (C=120, k =5.3x10+ m)

USE EXCEL  Water at 20 degrees celsius is to be pumped from a reservoir (ZA=2m) to another reservoir at a higher elevation (ZB=9m) through two 25 m long plastic pipes connected in parallel. The diameters of the two pipes are 3cm and 5cm. Water is to be pumped by a 68 percent efficient motor pump unit that draws 7kw of electric power during operation. The minor losses and the head loss in the pipes that connect the parallel pipes to the two reservoirs are considered to be negligible. Determine the total flow rate between the reservoirs and the flow rates through each of the parallel pipes

Part A A solar water heater mounted on the roof consists of two flat plates. Water enters at A and exits at B. Assume the average temperature of the water is 45°C. (Figure 1) If the gap between the plates is a = 1.58 mm, determine the maximum allowable pressure drop from A to B so that the flow remains laminar.
