600 kg of a liquid is to be heated from 15 ?C to 150 ?C in a well-stirred, jacketed tank by steam condensing at 170 ?C in the jacket. The heat transfer surface area of the jacket is 4.5 m2 and the heat capacity of the liquid is 1850 J/kg·K. The overall heat transfer coefficient, U, varies with temperature as follows:
T (?C) |
15 |
30 |
60 |
90 |
120 |
150 |
U (W/m^{2}·K) |
390 |
465 |
568 |
625 |
664 |
680 |
a) Calculate the required heating time.
b)Correlate the data in terms of the expre
where T is in degrees Kelvin, and calculate the required heating time.
