Water is being pumped from bottom of a well 15ft deep at the rate of 200gal/he into a vented storage tank to maintain a level of water in a tank 165ft above the ground. to prevent freezing in the winter a small heater put 3btu/hr into the water during its transfer from the well to the storage tank, assuming that the well water is at 35fahrenhiet? a 2-horsepower pump is being used to pump the water . about 55% of the rated horsepower goes into work of pumping and the rest is dissipated as heat to the atomsphere.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
