two pumping wells 1000 m away fully penetrate the same confined aquifer. one of the wells pumps at a rate of 1240 m3/day. the second well pumps at 850 m3/day.if the aquifer has a transmissivity of 2000 m2/day and a storage coefficient of 4x10^-4, when would the wells start interfering with each other.
If the difference in weight between the two baskets must greater than 15 lb they will not have the strength to operate the pulley. The King weighs 195 lb, the princess weighs 105 lb, and the prince weighs 90 lb.
a) The maximum flow rate that can be achieved without cavitation occurring in the piping system. b) The maximum elevation of the highest point of the piping system to avoid cavitation.
Determine the heights of the fluid columns for barometers that use the following liquids at 20 C: water, ethyl alcohol, and mercury. Why do you think mercury barometers were used in the past (before the negative health effects of mercury were know..
Water flows through a horizotal 45 deg reducing bend with a 36 inch. diameter upstream and a 24 inch diameter downstream, at the rate of 20 cfs under a pressure of 15 psi at the upstream end of the bend. Neglecting head loss in the bend, calculate..
