Oxygen is supplied to a medical facility from ten 3.2-ft compressed-oxygen tanks. initially, these tanks are at 2,400 psia and 80°f. the oxygen is removed from these tanks slowly enough that the temperature in the tanks remains at80°f. after two weeks, the pressure in the tanks is 100 psia. determine the mass of oxygen used and the total heat transfer to the tanks.

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

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
