A shell-and-tube heat exchanger containing one shell pass and two tube passes heats water moving at a mass flow rate of 2.52 kg/s from 20 degree C to 55 degree C by using hot water under pressure entering at 115 degree C and leaving at 50 degree C. The outside surface area of the tubes in the exchanger is Ao = 9.3 m2. Calculate the mean temperature
Heat Exchanger Design Example..(a) Objective:Design a double pipe heat exchanger with bare inner multi-tubes that can be used to cool engine oil with cold sea water. The following are the design specification:Fluid Engine Oil Sea Water Inlet Temperature, C 65 20
Hairpin Type Heat Exchangers & Double Pipe / Multitube Dec 16, 2020 · Hairpin heat exchanger will increase heat transfer coefficients in a single pass process streams with high temperature differentials. It is also known double-pipe or multitube heat exchangers, the hairpin heat exchanger has been used in process industries for many years. A Hairpin Heat Exchanger and Double Pipe / Multitube Heat Exchanger can be described as a single pass shell and tube unit that has been folded in half to give it a hairpin
The most basic and the most common type of heat exchanger construction is the tube and shell, as shown in Figure 1. This type of heat exchanger consists of a set of . tubes. in a container called a . shell. The fluid flowing inside the tubes is called the tube side fluid and the fluid flowing on the outside of the tubes is the shell side fluid
Section 5.4 Shell and Tube Heat Exchanger CorrectedShell-and-tube heat exchangers can have multiple passes, such as 1-1, 1-2, 1-4, 1-6, and 1-8 exchangers, where the first number denotes the number of the shells and the second number denotes the number of passes. An odd number of tube passes is seldom used except the 1-1 exchanger. A 1-2 shell-and-tube heat exchanger is illustrated in Figure 5.19.
Parallel, Counter and Cross Flow
Products Multi-Tube Hairpin Heat Exchangers Heat While the shell and tube heat exchanger is often described as the "workhorse of the industrial process industry, the multi-tube heat exchanger builds on the success as an immensely versatile unit, able to handle a wide range of process applications and conditions.
Shell and tube heat exchanger - Oil and Gas Production This is a double-pass exchanger. The shell-side fluid is limited to one pass within one shell and this type of exchanger is known as a 1-2 exchanger. Fixed Head 1 - 2 Exchanger. In this exchanger the tubes are held in tube sheets (one each end) and these tube sheets are fixed to the shell.
As you can see, in a 1-2 heat exchanger, the tube-side fluid flows the entire length of the shell, turns around and flows all the way back. It is possible to have more than two tube passes. Multiple shell passes also are possible, but involve fabrication that is more complex and is usually avoided, if possible.
Single, double or triple pass cooling - what's the Here we discuss the importance of single, double and triple pass cooling. Every shell and tube heat exchanger carries a flow of cooling water through its central tube core. But depending on its design, the water may flow through the unit once, twice or three times, which is done to get the optimum cooling performance for the available volume of cooling water.
