(a)
Expert Solution
Answer to Problem 1QAP
The repeat unit structure of polychlorotrifluoroethylene is sketched and shown in
Figure 2.
Explanation of Solution
The repeat unit of polychlorotrifluoroethylene is arrived from the repeat unit of polyethylene.
The repeat unit molecular structure of polyethylene is shown in Figure 1.
The repeat unit of polyethylene contains two carbon atoms and four hydrogen atoms.
The replacement of three hydrogen atoms by three fluorine atoms and one hydrogen atom by one chlorine atom gives the repeat unit molecular structure of polychlorotrifluoroethylene that is shown in Figure 2.

Required information Air at 25°C (cp=1006 J/kg.K) is to be heated to 58°C by hot oil at 80°C (cp = 2150 J/kg.K) in a cross-flow heat exchanger with air mixed and oil unmixed. The product of heat transfer surface area and the overall heat transfer coefficient is 750 W/K and the mass flow rate of air is twice that of oil. NOTE: This is a multi-part question.

- In an industrial facility, a counter-flow double-pipe heat exchanger uses superheated steam at a temperature of 155°C to heat feed water at 30°C. The superheated steam experiences a temperature drop of 70°C as it exits the heat exchanger. The water to be heated flows through the heat exchanger tube of negligible thickness at a constant rate of 3.47 kg/s. The convective heat transfer coefficient on the superheated steam and water side is 850 W/m²K and 1250 W/m²K, respectively. To account for the fouling due to chemical impurities that might be present in the feed water, assume a fouling factor of 0.00015 m²-K/W for the water side. The specific heat of water is determined at an average temperature of (30 +70)°C/2 = 50°C and is taken to be J/kg.K.
