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 Rusting of iron takes place Embrittlement of iron occurs Both B and C Here Emf produced is very low of the order of microvolt Rusting of iron takes place Embrittlement of iron occurs Both B and C Here Emf produced is very low of the order of microvolt ANSWER DOWNLOAD EXAMIANS APP
Process Control and Instrumentation The Laplace transform of exp(at), where a > 0, is defined only for the Laplace parameter, s > a since The Laplace transform integral of exp(at) has initial values only for s > a The Laplace transform of integral of exp(at) has finite values only for s > a The function is exponential The function exp(at) is piece-wise continuous only for s > a The Laplace transform integral of exp(at) has initial values only for s > a The Laplace transform of integral of exp(at) has finite values only for s > a The function is exponential The function exp(at) is piece-wise continuous only for s > a ANSWER DOWNLOAD EXAMIANS APP
