Two water pumps are connected in parallel and discharge a combined flow of 130 L/s into a single force main with roughness of 0.01 mm, and a total length of 1500 m. The force main connects two open water reservoirs. If the static head between the reservoirs is 12 m, and considering minor losses (K =1), calculate: a) Force main diameter, in mm. b) Pump head, in m. c) Flow rate delivered by each pump, in L/s The pumps' characteristic curves are given by: Pump 1: Hp = -0.00005Q³ + 0.0016Q² – 0.065Q + 32 Pump 2: Hp = -0.00005Q³ - 0.0009Q² – 0.040Q + 40 where Hp is in m, and Q in L/s.

You only know one point on a pump curve, where a water pump produces 20 m of hydraulic head at flow rate of 3.67 L/s, and you want to use this to pump water from a lower tank to an upper tank located 15 m higher. Both tanks are open to the atmosphere. Briefly explain your reasoning, in 1‐2 sentences, for each of the following. a) Should this pump be placed next to the lower tank or the higher one? b) Given the data point you have from the pump curve, will the flow rate be higher or lower than 3.67 L/s if the water is pumped exactly 15 m uphill?
Suppose the pump of Fig. is situated between two large water tanks with their free surfaces open to the atmosphere. Explain qualitatively what would happen to the pump performance curve if a valve in the piping system were changed from 100 percent open to 50 percent open, all else being equal. Repeat for the system curve. What would happen to the operating point—would the volume flow rate at the operating point decrease, increase, or remain the same? Indicate the change on a qualitative plot of H versus V. , and discuss.
Correct this problem with step-bystep please: A pump moves water horizontally at a rate of 0.02 m^3 /s. Upstream of the pump, where the pipe diameter is 90 mm, the pressure is 120 kPa. Downstream of the pump, where the pipe diameter is 30 mm, the pressure is 400 kPa. If the loss in energy across the pump due to fluid friction effects is 170 N.m/kg. Determine the hydraulic efficiency of the pump.
Water flows through a rubber hose 2 cm in diameter at a velocity of 4 m/s. (a) What must be the diameter of the nozzle in order that the water emerge at 16 m/s? (b) What is the rate of flow in cu.m per minute?
A Pelton wheel has a 12 feet diameter runner and operates under a net head of 2000 ft. Estimate the power output, in HP, for best efficiency if the nozzle exit diameter is 4 inches.
After graduation, you work for a pump manufacturing company. One of your company’s best-selling products is a water pump, which we shall call pump A. Its impeller diameter is DA = 6.0 cm, and its performance data when operating at n. A = 1725 rpm (?A = 180.6 rad/s) are shown in Table.The marketing research department is recommending that the company design a new product, namely, a larger pump (which we shall call pump B) that will be used to pump liquid refrigerant R-134a at room temperature. The pump is to be designed such that its best efficiency point occurs as close as possible to a volume flow rate of V. B = 2400 cm3 /s and at a net head of HB = 450 cm (of R-134a). The chief engineer (your boss) tells you to perform some preliminary analyses using pump scaling laws to determine if a geometrically scaled-up pump could be designed and built to meet the given requirements. (a) Plot the performance curves of pump A in both dimensional and dimensionless form, and identify the best…
An existing pump is used to pump water with the following data at BEP: D = 2.15 in, N = 1784 rpm, ρ = 998 kg/m3, Q = 18 gpm, H = 4.2 ft. A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches. Round off your final answer to 3 decimal places.
Q Consider the following data relating toperformance of a centrifugal pump:speed 1200 rpm, flow rate 30 L/s, head 20 m, and power 5 kW. If the speed of the pump is increased to 1500 rpm, assuming the efficiency isunaltered, Find the new flow rate and head.

Fluid Mechanics. plz, solve all the parts from a , b and c Reg.no : 5395 Pb # 6: At its optimum point of operation, a given centrifugal pump with an impeller diameter of 500 mm delivers a 4 m3/s of water against a head of (Reg.No/100) m when rotating at 1500 rpm. (a) If its efficiency is 82%, what is the brake power of the drive shaft? (b) If a homologous pump with a diameter of 800 mm is rotating at 1200 rpm, what would be the discharge, head, and shaft power. Assume both operate at the same efficiency. (c) Compute the specific speed of both pumps. What type of pumps are these?

A pump is to be made up with a number of stages in series of similar construction to that of the first pump to run at 1250 rpm and to deliver 15 kiloliters/min against a totalhead of 250 m. Find the diameter of the impellers and the number of stages required in this case. Answer: D = 46.63 cm, n = 6 stages
