HandyCalc Calculator

This is an engineering calculator type tool app. It is mainly divided into two modules:
1. Calculation of pump head design:
Calculate the head value of the effluent pump by inputting inlet pressure p1 (Pa), outlet pressure p2 (Pa), inlet flow velocity v1 (m/s), outlet flow velocity v2 (m/s), inlet height z1 (m), outlet height z2 (m), liquid density (kg/m ³), and gravitational acceleration (m/s ²).
2. Analysis of water, cement, sand, stones, and other materials required for preparing concrete:
Analyze the mass ratio of ingredients (water/cement/sand/stone) by inputting the volume of prepared concrete (cubic meter, m ^ 3), ingredient water, ingredient cement, ingredient sand, ingredient stone, and the selected scheme.
