Calculation programs

Following programs is developed by Integrated Drives Sweden AB to be used by everyone that need simple tools regarded to hydraulics calculations.

Program 1
CALCULATION OF PRESSURE DROP IN CONDUCTORS
Input values in yellow cells. Calculated values in green cells.
The Program make it possibly to calculate two alternatives at the same time. Two viscosities. Two oil density. Two conductor diameters. Single conductor or conductors in parallel. Different conductor length. Different flow. The program calculate pressure losses in high precision hydraulic pipes according to DIN 2391 C and assume the same inside surface roughness for hoses as for pipes.
Note the change in viscosity as function of temperature and the change of oil density as function of temperature.

Program 2
CALCULATION OF OPTIMAL ECONOMIC DIAMETER FOR CONDUCTORS

Input values in yellow cells. Calculated values in green cells.
The first part of the program is identical with Program 1 except that it's possibly to calculate 8 alternatives at the same time. The second part of the program make it possibly to make an optimal sizing of the piping based on price of pipes and hoses, labour costs for installation of pipes / hoses and depreciation costs.
Note the program do not involve sizing and costs of coolers as function of power losses based on conductor size.
