From the table, observe that the temperature in the tank 3, high temperature and low as possible, so we therefore find the appropriate speed to the speed of the closest cylinder 3.
Observed from the table Tank temperature to produce the three highest and lowest temperatures. So we find the right speed for the speed of the 3 tanks similar.
From the table, noticed that the temperature 3 tank production to high temperature and low So we can find the appropriate speed to the speed and 3 tank nearby
