The tank in figure below is filled through point 1 with velocity equal to 5 m/s and point 3 with volumetric flow rate equal to 0.012m3/s. If the level of the water h is constant, determine the exit velocity V2. If the water level h varies and V2 =8 m/s, find the rate change (dh/dt). Assume d=1m.

fluid flow between parallel plates (Fig. 2) that are horizontal and a distance 2h apart. A constant pressure gradient is applied in the x-direction (dp/dx). The flow is fully developed laminar and steady.
