(X Solve the problem. Round your answer, if appropriate. 15) Water is discharged from a pipeline at a velocity v (in ft/sec) given by v = 1200p(1/2), where p is the pressure (in psi). If the water pressure is changing at a rate of 0.267 psi/sec, find the acceleration (dv/dt) of the water when p = 59.0 psi. 10 ( /2 )
