Heatex Select enables calculations of the performance of our products under different conditions. Heat exchanger calculation made easy.
The tube sheet and shell at both ends of the heat exchanger are integrated, which makes it difficult to clean the shell side. Therefore, it is required that the fluid in the shell side be clean and scale-free, and the temperature difference between the two fluids is less than 70 C. U-...
This example shows how to design feedback and feedforward compensators to regulate the temperature of a chemical reactor through a heat exchanger. Heat Exchanger Process A chemical reactor called a stirring tank is depicted below. The top inlet delivers liquid to be mixed in the tank. The tank...
The differential temperature can vary through the heat exchanger. A mean value, LTMD, is used for calculation. It is called Δtm in the general formula above. It can be calculated by the following formula, using the denominations in Figure 6.1.8. In the example with the cheese milk heater...

It is a process value of the heat transfer in between a fluid and a body. For example from cooling water to the steel of a heat exchanger. The heat transfer coefficient depends only on the fluid, its movement and the surface of the solid body. However, not from the material of the so...

This method uses coupled models for calculation of the temperature and pressure fields, i.e., temperatures and pressures of both streams in each sub-exchanger, considering the variation of their physical properties and the axial heat losses Optimum results are obtained when the temperature field alon...
When I see hi and ho in a heat exchanger calculation I think of inside and outside heat transfer coefficient of the tubes. These units are W/m2.K (for example). Q has units of J/s and m kg/s. Therefore your equation is not dimensionally correct.You post should state what you are...
