I have an oil bath that has a jacketed heat exchanger I wish to use to heat another water bath. The temperature of the oil bath is 100 C and the water bath temperature I require is 54 C. My question is will this be either too much heat or not enough. My basic design is to use a thermistor to monitor water bath temp and adjust the pump speed (12V) accordingly. I think I have the circuit downpat but want some help with the theoretical heat capacity calculations. Without wanting to go and renivent the wheel I was hoping someone could run through some quick back of napkin calculations with me. Cheers.
