Calculate the water pressure in the pipes at the bottom if a high –rise building that is fed by reservoir 60 m above the roof top

What is the length x of the side of the triangle below? (hint: use the cosine function)

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.)
