John was told that for his first design project, he was to examine the uniform water flow (68 degree fareneheit) through a 6ft wide rectangular channel (n=0.015). the total distance of the open channel is expected to be 5000 ft with an elevation drop of 15 ft. for the gtiven perameters what would be the following characteristics of the open channel if the water depth is 2.5 ft, find channel slope, and hydraulic radius?

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
