Consider the mixing of 0.8 kg/s of hot water at 348 k and 1 kg/s of cool water at 298 k that is generating warm water. assume no work is being done and the system is in steady state, but heat is lost at the rate of 30 kj/s during this mixing. find the temperature of the warm water flow stream? assume cp =4.18 kjkg

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
