Process Engineering is much complex discipline in the field of Chemical Engineering. This field will challenge you like anything. While operating the process plant you may encounter with plethora of problems that need immediate attention, without which the result won't be pleasing.

LMTD, Log mean temperature difference is the temperature driving force for heat transfer in flow systems. When you are calculating heat transfer by overall heat transfer coefficient (U), you should not simply multiply temperature difference of hot stream or cold stream. Multiplying this temperature difference doesn't account the overall driving force.

Pressure drop due to valves and fittingsIn the earlier post, tutorial goes around pressure drop in pipe lines. Pressure drop arises due to skin friction and form friction. Non separated boundary layers cause skin friction whereas separated boundary layers cause form friction. In plain pipe pressure drop is due to skin friction. But in a pipe line with valves and fittings pressure drop is mainly due to form friction. the pipe lines may be connected to equipment and again pressure drop will be there in that equipment. This tutorial is restricted to pressure drop in valves and fittings only.

Earlier two parts of designing a P&ID were from process perspective of a P&ID. Now in this present part we will deal with the instrument aspects of a P&ID. Some of the most common instruments which we are using in process industry are transmitters, gauges, indicators, control valves, on off valves etc. The parameters which we are interested may be flow, temperature, pressure, concentration etc. Before going to discuss further about instrumentation part in P&ID it is better to get familiarized with the instrumentation terms. Let’s get started
