you have develope a super heat sotrage fluid and now need to determine its heat of vapoirization you set up an experiment with 60m cylindrical copper tube. the fluid enters the tube at 130 C at 100% vapor and exits at saturated liquid. the outer surface is exposed to water at 25C with a heat transfer coefficient of 200 W/m^2k. The inner surface heat transfer coerfficent is 350 W/m^2k. The inner tube diameter is 20 cm and the tubing is 2cm thick. If the mass flow rate is 0.1 kg/s. what us the heat of vaporization.

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
