Glucose syrup is heated to 75°C in a cylindrical stirred jacketed vessel. The vessel has an inner diameter of 1.3 m, height of 1.8 m, and is 70 % filled with Glucose syrup. The heating medium in the jacket is at 100°C and the initial temperature of the syrup is 30°C. The overall heat transfer coefficient is 300 W/m2 K. The density and heat capacity of the syrup are 1220 kg/m3 and 3.3 kJ/kg.K respectively.
a) Calculate the time to heat the glucose syrup from 30°C to 75°C.
b) What assumptions do you need to consider for these calculations and why?
