we made an experiment to determine the diffusivity of HCl in air by knowing the Temperature, Distances moved by HCl molecules and correspondent times, the temperature of air inside the tube was equal to 27.8°C, and the procedure were: Five indicators (Litmus papers) were put inside the glass...
let's say the maximum outside temperature is 50°C, and knowing the saturated pressure from the steam tables i found that the saturated temperature is 184.154°C. if i chose fiberglass for insulation, which has an emmisivity of 0.75, and a thermal conductivity of 0.06 W/m.K at 184.154°C, and if we...
hello everybody, I'm new here and i have this homework which i don't know how to solve it, please help me:
Design the thickness of insulation for steam pipe of:
-Pipe diameter 2 in.
-Pipe length 200 m.
-Saturated steam pressure 10 bar.
-Ambient temperature 30°C.
-Steam cost $4.5/MMbtu
