Fluid properties tool is accessible from the side menu, by clicking on the button with fluid-bank icon.
Fig. 1: Pressure drop tool window
The pressure drop tool will appear in the new window.
Input values:
- Heat exchanger
State the heat exchanger you want information about. You may choose a heat exchanger from the dropdown. Only one heat exchanger can be selected at a time. - Fluid
If anything else than water is stated, you must also enter the density and viscosity of the fluid. - Number of passes
The required number of passes. Default = 1. The maximum allowed number of passes is 6. - Number of channels
The minimum allowed number of channels is 1 and the maximum is 999. - Reference temperature
The required reference temperature for water. Value range: 0 to 250°C (32 to 482°F). - Specific pressure drop calculation
If you want to know the flow rate for a specific pressure drop or vice versa, use this feature .Just fill in one of the values and get the corresponding value in other textbox
- Range of pressure drop calculation
Press'Calculate range' and the flow rate will be calculated for the given range and vice versa. The range is editable.
By selecting a column in the grid either pressuredrop or flow the grid column will become gray, which is considered as the input for calculation.
Calcualtion range allows exporting or pasting data from MS Excel. For exporting the calculated list into MS Excel, it's just needed to mark the list and copy (Ctrl+c) and paste (Ctrl+v) when you moved to the Excel sheet. For pasting data from MS Excel, the process is contrary.
Features available when calculation is done:
- Print
To get the printout of the calculated range in the list and the graph displayed press print report in the toolbar at the top of the screen.
- Graph [pressure v/s flow]
It is an add-on feature available in Pressuredrop, based on the calculation range displayed in the list, a graph is plot between the pressuredrop and flow rate and is displayed on the right side of the form. The graph can be plot between Pressuredrop v/s flow and flow v/s pressuredrop by choosing it from the dropdown provided in the top toolbar.
- Unit conversion
The units of pressuredrop and flow can be changed in the grid by changing the units in the Pressuredrop textbox and flow textbox respectively.
