The monthly pan evaporation measured in a lake for the month of January was 16.7 cm. If the average water surface area is 2.55 km^2 , estimate the evaporation loss that month in cubic meters if the pan coefficient is 0.70?
Water is flowing in a 100 mm diameter Mild Steel (MS) pipe of length 180 m as shown in the figure. The reservoir water level remains constant. Determine the flow rate. Use Darcy Weisbach formula with loss coefficient method and Darcy Weisbach formula with effective pipe length method.
In the figure shown, water (ν = 1 x 10-6 m2/s) flows at a rate of 5 L/s on a system of pipes. There are 40 m of 50-mm diameter pipe, 22 m of 150-mm diameter pipe, and 45 m of 75-mm diameter pipe, all cast-iron. There are two 90o elbows and an open globe valve. If the exit elevation is zero, determine the following:a) friction loss on each pipeb) total minor loss from the surface of the reservoir to the exitc) head extracted by the turbined) mechanical power extracted by the turbine
Sparky created a pumping system between Hydaway Lake and a holding pond on the Snowflex property. The water is used to create a fine mist on the tubing/snowboarding/ skiing surfaces. There is a pump in the system that delivers 250 ft of head to the water. The difference in elevation between the two ponds is 200 vertical ft. The various minor head loss coefficients are shown in the figure. Additional data for the problem is also included in the figure. The water temperature is 60°F. Sparky knows the flow in the system must be turbulent but does not know how to determine the pump power. Determine the pump power. This is an iterative problem; thus you must set up the equations and define the process used to generate a final solution. Define the symbolic equation then substitute in numerical values that you have or can calculate. Start with the fluid energy equation that includes major (Reynolds Number dependent) and minor head losses. You are not required and should not…
As shown in the figure below, a pump lifts water through a 100-mm diameterductile iron pipe (friction factor f = 0.0251) from a lower to an upper reservoir. If the differencein elevation between the reservoir surfaces is 10 m, and the pump performance curve is givenby H = 15 – 0.1Q2, where H is in m and Q in L/s.a. Determine the system head curve (relationship between TDH and Q) assuming theentrance and exit loss coefficients are both 1b. Estimate the flow rate through the systemc.
