This custom Excel spreadsheet calculates the resultant force on a boat based on user provided information about wind, current, tidal stream, and charted course and speed for the boat, along with user provided information about boat dimensions. The speed and course of the boat due to all of the calculated forces is also calculated.
This is a custom spreadsheet for calculating the required dilution ratio for specified chemicals present in a laboratory fume hood.
This is a custom spreadsheet prepared to make specific stage-storage calculations.
This is a custom spreadsheet for estimating the water evaporation rate from a sump.
A custom spreadsheet for soil storage calculations.
This spreadsheet calculates the minimum pipe bend wall thickness using ASME B31.3 equations, based on user input values for several required parameters. There is a worksheet for calculating the minimum wall thickness at the inside radius (intrados) and a worksheet for calculating the minimum wall thickness at the outside radius (extrados). The worksheets are set up to use S.I. units
This Excel Workbook is set up to calculate the capacity of a stormwater inlet based on input values for inlet dimensions and stormwater depth at the inlet. There is a worksheet to make the calculations for a curb inlet and a worksheet to make the calculations for a gutter (grate) inlet. Information is also provided in the workbook on how to handle the calculation of inlet capacity for a combination inlet.
This is a custom spreadsheet that calculates the required air dilution flow rate in SCFM and in ACFM for specified values of gas leak rate in SLPM, IDLH in ppm for the gas that is leaking, dilution air temperature and pressure, and values for standard temperature and pressure.
This spreadsheet uses the Freundlich Isotherm equation to calculate the capacity of granular activated carbon for removal of a user specified organic compound from water.
