PLC (Programmable Logic Controller) programming allows a computer to automate mechanical or electrical processes for machinery, lighting, or assembly line control actions. Over the past two decades, PLC programming has been used in a number of industries. The PLC’s design allows it to take multiple inputs and provide various outputs. A PLC device is also referred to as a hard, real-time control system since its output(s) is in direct response to input conditions within a pre-arranged time frame.

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
