What is the Difference between Fanning friction factor and Darcy friction factor? Fanning friction factor The Fanning friction factor is defined as follows: ff = fd /4 Where; ff =Fanning friction factor fd =Darcy friction factor Darcy friction factor The Darcy friction factor is defined as follows: fd = 4 […]
Hazen-Williams equation is a popular approach for the calculation of head loss of liquid in piping systems. In this method, Hazen-Williams coefficient is introduced to the equation, the coefficient eliminates the need for using Reynolds number. The Hazen-Williams coefficient is mainly used to account for the pipe roughness or efficiency.
Common causes of overpressure below is a list of Common causes of overpressure in process operation. Utility failures, including: General power failure Partial power failure Loss of instrument air Loss of cooling water Loss of steam Loss of fuel gas or fuel oil. Loss of cooling duty, caused by: Loss of […]
This short articles describes how to find how many shells needed in series that would be sufficient to perform the duty required.
What is a heat exchanger? A device to exchange the thermal energy between two or more fluids at different temperatures. In simple terms; if you want to use a hot fluid to heat up a colder one you can use a heat exchanger to do the job. Heat exchangers are […]
Shell and Tube heat exchanger uses Shell and Tube Heat Exchangers are the most commonly used in the chemical processing industries today. It possesses large surface areas for heat transfer and is capable of operating at high temperatures and pressures. Shell and tube heat exchangers are frequently selected for applications […]
What is a Plate Heat Exchanger? Plate heat exchangers are essentially a number of pressed metal plates, aligned on a frame clamped together with gaskets between the plates. Each pressed plate is corrugated, having a number of alternating ridges and grooves. The pattern and geometry of the corrugations are a […]
Quick description What is a double pipe heat exchanger? Double pipe heat exchanger is perhaps the simplest of all heat exchanger types. Double pipe heat exchangers are also known as hairpin, jacketed pipe, jacketed U-tube and concentric pipe. These styles of double pipe may have a bundle of inner tubes rather […]
Recommended shell and tube side velocities values are listed below, the values can be used for preliminary design purpose when designing shell and tube heat exchangers, these are guidelines that are in place as lower velocities can cause fouling issues and very high velocities can cause erosion issues. If there […]
How to use shell and tube heat exchanger software effectively? This short article aims to give some recommendations and guidelines on how to effectively use shell and tube heat exchanger software (S&THex) effectively to design a heat exchanger, the article may also answer questions such as how do I know […]
