Aflorida spring supplies water at a temperature of 18 oc. this water mixes with a creek that delivers water at 23 oc. the combined stream has a temperature of 21.5 oc, with a combined flow rate of 1000kg/s. find the flow rate of the spring and the creek. how much entropy is being generated per second due to the heat transfer?

What precautions should you take to prevent injuries when dealing with heavy loads?

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

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
