Problem 4 -15 marks You have been assigned to collect thermodynamic data for a new liquid product your company is about to begin manufacturing. You decide to use a continuous-flow technique to generate a correlation of H versus T. You wrap an electrical heating tape around a pipe, cover the tape with a thick layer of insulation, pump the liquid through the pipe at the rate of 228g/min, and adjust the power input to the heating tape with a variable resistor. For each resistance setting, you record the power input and the temperature of the liquid at the pipe outlet. You multiply the power input by a correction factor of 0.94 to determine the rate of heat input to the liquid. The entering fluid temperature remains at 25C throughout the experiment. The following data are taken: 1. Generate a table of H(J/g) versus T(C), taking 25C and 1 atm as the reference state. 2. Fit a line to the data (either graphically or by the method of least squares) to determine the coefficient b of an expression of the form H^=b(T25). 3. Estimate the heat input required to raise 350kg/min of the liquid from 20C to 70C. Why would you be concerned about the accuracy of your estimate
