Please provide the answer for the following question

"The designed temperature of the reactor is 70C. The target reactor temperature is 50C(1C). The feed enters at the top of the column (Stream 50). The reactor temperature is manipulated by controlling the flow rate of the Cooling Water Inlet (Stream 100) entering the Reactor (RXT101) via a Cooling Water Pump (PMP101). The Reactor Temperature Transmitter (X101) is mounted on the reactor and is used to measure and transmit the temperature that is in the Reactor (RXT101). The Reactor Temperature Transmitter (X101) sends a signal to the Reactor Temperature Controller (Y101) that is remote in the control room. The reactor temperature can be monitored by the operator only in the control room, displayed on the controller (Y101). The controller (Y101) sends a signal to the final controlling element, a variable speed Cooling Water Pump (PMP101) to maintain the reactor temperature within the operating range of 45-55 Task: What is X,Y and Z ? Please update the C by adjusting the cooling water flow rate. There is a P\&ID drawing. As this is considered a draft locally mounted Cooling Water Flow Transmitter (Z101) version, any alarms can be omitted, and with a display for the operator to read the flow rate at any hand-drawn submission is accepted. time. The product A exits (Stream 51) out of the reactor However, submission should still follow (RXT101) to a storage tank." standard conventions, legend sheet and title block
