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
tell me the field & lab calibration procedure step by step with diagram of pressure gauge, pressure switch, pressure transmitter, temperature switch, level switch, flow switch, flow transmitter, temperature transmitter, temperature indicator, flow indicator, level indicator, control valve, thermocouple, pressure indicator (digital & analogue),
Which are all the commonly used Bordon tubes in the pressure gauges. Do any one use ASTM A 312 tubes for this purpose?
you are on site,the plant trips,you are approached by operations,what do you do?
In control valve proximity inductive sensor is taken as digital feedback for full open and full close.Normally its volts 24v when the sensor acts the feed back voltage 14v so that our relay not indicating in plc panel . kindly give the solution.
