QuickPipe app for iPhone and iPad

QuickPipe is dedicated for the calculation on fluid properties such as temperature, energy change, heat transfer, pressure loss and etc for pipes/tubes/hoses. The database consists of more than 50 different fluids, more than 200 different metal tubes/pipes and more than 200 different plastic pipes. With such database of wide coverage, QuickPipe can help engineers perform following calculations with ease.
1. Obtain the amount of heat transfer (aka energy change) based on temperature differences. (Alternative control parameters including both mass and volume of fluid.)
2. Obtain the heat transfer rate based on temperature differences. (Alternative control parameters including both mass and volume flow rates of fluid.)
3. Determine temperature differences from the amount of heat transfer in a closed system.
4. Determine temperature differences from the heat transfer rate in a dynamic system.
5. Check the nominal sizes, DN, outside diameter, internal roughness and weight per ft of various tubes/pipes.
6. Obtain the unit pressure loss of each pipe/tube/hose selected based from the values of the current flow rate and pipe/tube/hose length input by users.
7. Calculate the overall pressure loss based on the pipe/tube/hose length along with the numbers of 90° Ells, 45° Ells, side branch of Tee, straight run of tee, couplings, ball valves, gate valves, butterfly valves and check valves.
8. A complete unit database allows the user to select the most familiar units of energy, heatload, pressure, length, flow rates and etc.
9. An user-friendly interface to allow the change on the settings of the pressure Loss in Fittings and Valves expressed as equivalent length of tube/pipe/hose.

流体工具箱是特別针对流体相关设计人员, 维护管理及操作人员的需求, 而设计之快速计算工具。可以立即计算吸放热与温度变化,传热量与温度变化,管路单位压损值及管路总压损。资料库内内建有超过50种不同的流体,超过两百种不同的金属管以及超过两百种不同的塑胶管。使用者可以利用如此详细的资料库来进行以下的快速运算:
