The velocity of water ft/s at the point of discharge is given by v = 14.640-√P, where P is the pressure lb/in² of the water at the point of discharge. Find the rate of change of the velocity with respect to pressure if the pressure is 20.000 lb/in². Round to three decimal places. lb/in² OA. 32.736 ft/s per OB. 0.366 ft/s per lb/in² O C. 3.274 ft/s per lb/in² OD. 1.637 ft/s per lb/in²
