Water is ponded behind a vertical gate to a height of 5 m in a rectangular channel of width 8 m. Calculate the gate opening that will release 50 m3/s through the gate. How would this discharge be affected by a downstream flow depth of 4 m?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?
