The temperature is controlled with a P controller with Kc
= 1. Being given a disturbance of the input temperature from 50 to 60 C, calculate the
extra energy consumption due to the steady state offset. The characteristics of
the equipment in the control loop are:

final control element –

transducer –

process – nominal flow through the heat exchanger –  density of the fluid

specific heat  heat transfer coefficient  heat transfer
area AT = 1 m2.

What is the offset and the extra heat consumption if the
setpoint is changed with +10oC?
