You have been assigned to collect thermodynamic data for a new dialysis liquid your company is about to begin manufacturing, for use in systems such as the apparatus analyzed in assignment 1. You decide to use a continuous-flow system to generate a correlation of H vs T. You wrap an electrical heating tape around a pipe, pump the liquid through the pipe at 228g/min, and record the temperature at the outlet of the pipe for various electrical power inputs. The liquid enters the pipe at a temperature of 25°C. The data is shown below. Heat input to the Tout (°C) liquid (J/s) 25.0 0.0 26.4 17.0 35.3 27.8 29.0 50.9 32.4 94.4 a) Generate a table of H (J/g) vs T (°C), taking 25°C and 1 atm as the reference state. b) Fit a line to the data to determine the coefficient b of an expression of the form H = b(T - 25) c) Estimate the heat input required to raise 350 kg/min of the liquid from 20°C to 70°C.
