A 1-inch storm event causes runoff which feeds into a stream. In the 1.5-mile reach of the stream, the initial inflow at t1is 330 cfs and the rate of outflow is 245 cfs. After 3 hours, t2, the inflow and outflow are 210 cfs and 105 cfs, respectively. The storage at t2has been observed to be 29.5 acre-feet. Assuming a linear change in flow rates over this time period, determine the change in storage in 3 hours and the initial storage volume (allin acre-ft)

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Steam enters a converging nozzle at 3.0 mpa and 500°c with a at 1.8 mpa. for a nozzle exit area of 32 cm2, determine the exit velocity, mass flow rate, and exit mach number if the nozzle: negligible velocity, and it exits (a) is isentropic (b) has an efficiency of 94 percent
