Question 486

Multiple Choice

Solve the problem. Round your answer, if appropriate.
-Water is discharged from a pipeline at a velocity v\mathrm { v } (in ft/sec\mathrm { ft } / \mathrm { sec } ) given by v=1936p(1/2\mathrm { v } = 1936 \mathrm { p } ( 1 / 2 ) , where p\mathrm { p } is the pressure (in psi) . If the water pressure is changing at a rate of 0.373psi/sec0.373 \mathrm { psi } / \mathrm { sec } , find the acceleration (dv/dt) of the water when p=60.0psi\mathrm { p } = 60.0 \mathrm { psi } .
