WebThe values t1 and t2 are the times where the response attains 28.3% and 63.2% of its final value. You can use these values to estimate the time constant tau and dead time theta for the heat exchanger: t1 = 21.8; t2 = 36.0; tau = 3/2 * ( t2 - t1 ) theta = t2 - tau. tau = 21.3000 theta = 14.7000. the picture house leighton buzzard
