## Most Viewed Posts. # SMALL HYDRO POWER DESIGNER v1.1. SMALL HYDRO POWER DESIGNER V1.1 is an excel workbook equipped with useful design tools for feasibility level analyses / designs of high and medium head hydropower projects (upto 15 MW). However, the user can modify the workbook to include additional modules suited for larger projects. SHPD can assist in quickly producing layout alternatives, making reasonable cost estimates / cost comparisons for these alternatives and preparing concrete outline drawings of major structures using AutoCAD. SHPD is a freeware intended for engineering students as well as practising hydropower engineers. A user interface is also provided for assisstance of new users. The workbook and interface both have been created using Excel 2007 Professional Plus (vista) and are ensured to work correctly only for the same version. Typical layout of small hydro components adopted in SHPD is like this;. ### Related posts:. ### Civil Engineering Spreadsheets. Copyright © 2026 The Engineering Community | The Engineering Community.

Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! ## Power potential vs. ### Online Hydro-power Calculator. The calculator below can be used to calculate available hydroelectricity power. The theoretically power available from falling water can be expressed as. *Pth = ρ q g h (1)*. *ρ = density (kg/m3) (~ 1000 kg/m3 for water)*. *q = water flow (m3/s)*. Download and print Hydro Power vs. The theoretically power available from a flow of *1 m3/s* water with a fall of *100 m* can be calculated as. *P = (1000 kg/m3) (1 m3/s) (9.81 m/s2) (100 m)*. Due to energy loss the practically available power will be less than the theoretically power. Practically available power can be expressed as. ### Energy from Hydro-power. The potential theoretical energy in a volume of elevated water can be calculated. *V = volume of water (m3)*. The potential energy in the water volume can be calculated as.
