A water tank is gradually losing heat and its temperature drops by 4°K per minute. When the
heater is on, the system gains temperature at 2° K per minute. A two position controller has a .5
minute control lag and a neutral zone of±2% about a set point of 354° K. Plot the temperature
versus time graph and find the oscillation period. Assume at t=o, temperature is at set point and
the heater is on.
