60 cm diameter well is being pumped at a rate of 1360 litres/minute. measurements in a nearby test well were made at the same time as follows. At a distance of 6 m from the well being pumped, the drawdown was 6 m, and at 15 m the drawdown was 1.5 m. The bottom of the well is 90 m below the ground water table.

(a) Find out the coefficient of permeability.

(b) If all the observed points were on the Dupuit curve, what was the drawdown in the well during pumping?

(c) What is the sp. capacity of the well? (d) What is the rate at which water can be drawn from this well?

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate...

Water at 200 Fahrenheit is pumped from a storage tank at the rate of 50 gallons/minute. The motor for the pump supplies work at the rate of 2 hp. The water goes through a heat exchanger, giving up heat at the rate of 40,000 BTU/minute(Q Net In), and is delivered to a second storage tank at an elevation 50 feet above the first tank. What is the temperature of the water delivered to the second tank?

Drag measurements were taken for a 5 cm diameter sphere in water at 20 °C to predict the drag force of a 1 m diameter balloon rising in air with standard temperature and pressure. Given kinematic viscosity of water (v) = 1.0 X 10-6 m2/s and kinematic viscosity of air (v) = 1.46 X 10-5 m2/s. Perform the Buckingham Pi theorem to generate a relationship for FD as a function of the independent variables. Assume the drag FD is a...
