3. In a rectangular channel with width 4.0 feet and discharge of 12 cfs, a sluice gate which has an opening of 1.5 inches. The slope of the channel is 0.3% and the Manning number is 0.03. There is a free overfall over a 2 foot riser 120 yards from the sluice gate. a. What is the conjugate depth and length of the jump assuming the upstream depth is the same as the sluice gate opening? b. How much energy is dissipated during the jump?

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
