Process Control and Instrumentation Ordinary mercury in glass thermometer is used for measuring temperature upto 120°C. However, for measuring higher temperature upto __________ °C, thermometer is made by filling nitrogen under pressure above the mercury, which stops the evaporation of mercury and reduces the chance of broken thread of mercury. 350 250 550 700 350 250 550 700 ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation Suppose that the gain, time constant and dead time of a process with the following transfer function:Gc(s) = 10 exp( - 0.1s)/(0.5s + 1) are known with a possible error of ± 20% of their values. The largest permissible gain Kc of a proportional controller needs to be calculated below taking the values of process gain, time constant and dead time as 12, 0.4, 0.08 8, 0.6, 0.12 12, 0.6, 0.12 8, 0.6, 0.08 12, 0.4, 0.08 8, 0.6, 0.12 12, 0.6, 0.12 8, 0.6, 0.08 ANSWER DOWNLOAD EXAMIANS APP
