thank you.

The velocity of water it/s at the point of discharge is given by v= 13.580VP. where P is the pressure lb / in of the water at the point of discharge. Find the rate of change of the velocity with respect to pressure if the pressure is 70.000 lb / in Round to three decimal places. . . . .. A. 56 809 ft/s per lb/in O B. 0.097 fu/s per lb/in O C. 0 812 ft/s per lb/in O D. 1.624 ft/s per lb/in
