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

Why is it so difficult to process MSW?

An elevator has a rated capacity of 2200 lb. It can transport people at the rated capacity between the first and the fifth floors, with a vertical distance of 15 ft between each floor, in 7 s. Estimate the power requirement for such an elevator.

Refer to Figure 7.24. The following data were collected during the field permeability measurement of a confined aquifer using a pumping test. Determine the hydraulic conductivity of the permeable layer. Use Eq. (7.49). Thickness of the aquifer, H = 4.5 m Piezometric level and radial distance of the first observation well: h1 = 2.9 m; r1 = 17.8 m Piezometric level and radial distance of the second observation well: h2 = 1.8 m; r2 = 8.1 m Rate of discharge from pumping, q = 0.5 m3/min
