A well 300 ft deep is proposed in an aquifer having transmissibility of 12000 gpd per foot width of aquifer and a coefficient of storage of 0.006. The static water level is expected to be 100 feet below the ground surface, the well is pumped at 600 gpm and the well diameter is to be 12 inches. What will be the pumping lift from the well at the end of 2 years

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
