answer the four questions please

Final control element Flow Controller 1/P convertor (Control valve) How measuring element Process Flow transducer/ transmitter (Magnetic flowmeter) Questions: 1. Define the controlled variable, manipulated variable and potentin disturbances in flow rate experiment. 2- Describe the change in the output signal% of the automatic flow controller in case a. The bypass valve (V-05) was suddenly opened. b. PI speed has been reduced. c. Air supply to the control valve (air to open valve) has failed. d. Liquid level in tank (B1) was significantly reduced. 3-How can fluid volumetric flow be calculated based on its velocity? 4- Describe the change in the discharge pressure of the pump as water flow increases assuming that the pump is running at a fixed speed and the flow is throttled with the control valve
