##### Reference no: EM131069475

A newly hired chemical engineer at Hypothetical Industries is responsible for monitoring and maintaining temperatures for one of the company's exothermic reactions. The process uses a platinum resistor thermometer to measure the temperature of the process, the properties of which are given below. The reaction's ideal range is between 250°C - 350°C. Below 250°C, the catalyst ceases to function, and above 350 °C, it can be classified as a runaway reaction. The engineer can control steam and cooling water to regulate the process temperature.

Describe what changes the engineer should make to either the flow rate of the coolant or the steam to keep the system functioning optimally.

Case I: RT = 25ohms

Case II: RT = 13.9ohms

Case III: RT = 19.4ohms
