The 500 kg load on the hydraulic lift shown in the figure is to be raised by pouring oil (ρ = 780 kg/m3
) into a thin tube with 1 cm diameter. Determine how high should be
order to begin to raise the weight.

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)
