A computer in a well-sealed and well-insulated (thermally) room, dissipates energy at a rate of 500W. The room has 10 mw kg of drinking water, and 50 ma kg of air, with all material at 300K and 100kPa initially. Assuming all the mass (water and air) heats up uniformly, how long will it take to increase the temperature 5 dT °C?.
In an experiment, the temperature of a hot gas stream is to be measured by athermocouple with a spherical junction. Due to the nature of this experiment, theresponse time of the thermocouple to register 99 percent of the initial temperaturedifference must be within 5 s. The properties of the thermocouple junction are k =34 W/m·K, ρ= 8400 kg/m3 and Cp =310 J/kg·K. If the heat transfer coefficientbetween the thermocouple junction and the gas is 230 W/m2·K, determine thediameter of the junction. Answer: 0.59 mm
