**Centrifugal Pump Cavitation Calculation and Placement****Problem Statement:**The vapor pressure of water at 25 degrees Celsius is 23.8 mmHg. The atmospheric pressure is 14.6 psi. In the system shown below, in order to avoid cavitation, what should be the relative location of the pump (\(Z_a\)) if the total head loss from reservoir surface to pump entrance is 8.3 m? The pump is a Taco® Model 5009 centrifugal pump (diameter of 9.25 in. and operating at 1160 rpm) with a discharge of 750 GPM. Hint: Use the performance curves in Problem 2 for the pump.**Diagram Explanation:**A schematic of a pumping system is shown in the diagram. Key components are labeled as follows:- **Reservoir**: Positioned at the bottom left, denoted with a free surface with an elevation labeled as \(Z_a'\).- **Pump**: Positioned at a higher elevation between point \(a\) and \(b\), connected by pipes to the reservoir.- **Piping System**: Connects the reservoir to the pump and continues from the pump outlet to point \(b'\), including variations in height (\(Z_b'\)).- **Elevation Differences**: Indicated by various height markings across the system, which factor into head loss calculations.**Choices Provided:**- The pump should be located at least 1.99 ft above the water surface in the reservoir.- The pump should be located at least 1.99 ft below the water surface in the reservoir.- The pump should be located at least 3.78 ft above the water surface in the reservoir.- The pump should be located at least 3.78 ft below the water surface in the reservoir.These options suggest different scenarios for pump placement relative to the reservoir's water surface, highlighting the need to avoid cavitation by ensuring sufficient net positive suction head (NPSH).
