About Us

Engineering Excel Spreadsheets specializes in providing low cost, easy to use Excel spreadsheet templates for calculations that are tedious to perform by hand, but are not so complicated as to justify the purchase of an entire standalone, general-purpose program or to justify the time needed to learn how to use such a program.   With our spreadsheets, if you can type data into a spreadsheet cell, you can quickly get the answer you seek – no need to study tutorials, examples or Help screens.  To see the spreadsheets available, go to our Spreadsheet Store. We also provide supporting, informational articles about the use of Excel spreadsheets for engineering calculations.

Spreadsheets are available in several categories including : calculation of convection heat transfer coefficients, pipe flow calculations, pipe flow rate measurement with orifice and venturi flow meters, open channel flow, stormwater calculations, partially full pipe flow, wastewater treatment process design calculations (including activated sludge, MBBR, SBR, and MBR processes) and structural analysis of beams.
