The calc sheet made by SF Pressure Drop 7.0 shows wrongly values. For instance, flow 60m3/h, water, 20°C, and Pipe size 150. The velocity calculated is 943140403507528, and similar result for Renold number, pressure drop, etc.
I have installed the latest version of the software and everything worked correctly. I managed to select a pipe and do its calculations then I compared the results with the ones from the Help menu. There was no value reported as being incorrect. Your problem can be a bug in the application's code or an error in the values used to calculate. Additionally, use version 8 instead of 7.
