The Kishwaukee river has a volume flow rate of 21 ft3/sec with a depth of 2.8 ft. If the cross-sectional shape were assumed to be a trapezoid with surface 11.5% larger than the river bottom, then estimate the span from one bank to the other when the velocity is 3.4 ft/s.

Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.
