c) A linear sensor-transmitter is used in the flow control loop. The current transmitter output is at 8 mA when the flowrate in the pipeline is 5 m³/hr. Calculate the gain of the sensor- transmitter if the lowest value of the calibrated flow sensor is 0 m³/hr. Determine the range of the calibrated flow sensor.
