close valve A, open valve B, and repeat the procedure. Stop the pump and open valves A, B, and C again to make sure that the air has been purged from the system, then close valve C.Close the valve to the magnetic flow meter and open the valve to the rotameter. For five different flow rates, measure the flow rate, suction and discharge pressure, power, voltage, and current to the motor, force exerted by the motor on the spring (by the torque-arm), and the pressure drop across the piping system using the manometer. Close valves A and B, then close the valve to the rotameter and open the valve to the magnetic flow meter. For 5 different flow rates, take the same measurements as were taken with the rotameter, except pressure drop, which is now measured using the pressure gauges on the piping lines.Close the valve to the piping system and open the bypass line valve to the tank (the rightmost valve to the tank in Figure 1). Repeat the measurements using the magnetic flow meter to regulate the flow, with the exception of the pressure drop, which does not need to be measured in this section of the experiment.Turn the pump off, lock out the power to the pump as discussed in Appendix C (Lab Manual), and disconnect the motor from the pump. Turn the power back on, turn on the motor, and measure the power, voltage, and current of the motor during this no-load condition. Turn the motor off, lock out the power, reconnect the motor to the pump, turn the power back on, and turn on the pump to make sure it is working properly. Take a sample of the ethylene glycol solution and measure both the specific gravity and the temperature.A sample data sheet is shown below:Liquid temperature (C)______________Liquid S.G.______________Static head (psi)_______NO-LOAD CONDITIONSWattage (watts)_______Voltage (volts)_______Current (amps)_______Spring Force (lbf)_______PIPE SYSTEMFlow rate (gpm)___________________________________(Rotameter)Suction pressure (psi)_...
