Process Control and Instrumentation In a second order under damped system, the Time required for the response of first reach its ultimate value is called the response time Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot None of these Time required for the response of first reach its ultimate value is called the response time Overshoot (which is a measure of how much the response exceeds the ultimate value) increase with the decrease of damping co-efficient e Decay ratio (which is the ratio of the sizes of successive peaks) is equal to the reciprocal of overshoot None of these ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation Temperature measurement range of iron-constantan thermocouple is 0 to 870°C. It can be used to measure sub zero temperature, because at lower temperature Embrittlement of iron occurs Emf produced is very low of the order of microvolt Rusting of iron takes place Both B and C Here Embrittlement of iron occurs Emf produced is very low of the order of microvolt Rusting of iron takes place Both B and C Here ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation Continuous flue gas analyser makes use of paramagnetic properties of some of its constituents, which move towards the strongest part of the magnetic field thus displacing diamagnetic gases.
