Figure P4.7 shows a rigid vessel with input volumetric-flow rate. Qin. The hydraulic fluid has fluid bulk modulus = 1.2(109) Pa. At the instant shown the pressure in the chamber is P = 1.8(106) Pa, temperature is T = 345 K, and the volumetric-flow rate is Qin=2.4(106) m/s. Hydraulic fluid volumetric-flow rate Qin P V=0.006 m Rigid chamber a. Compute the fluid capacitance C of the hydraulic system. b. Compute the time-rate of pressure dP/dt at this instant. Figure P4.7
