工程流体力学常用公式电脑计算程序

COMPUTING PROGRAME FOR COMMON-USED FORMULAS OF ENGINEERING FLUID MECHANICS

提供了工程流体力学常用公式电脑计算程序，利用这些程序可以快速、准确地计算管道的压力损失、摩擦压力损失系数、流速、雷诺数，求管道直径，或者求紊流过渡管区摩擦压力损失系数，并指出流体的流动性质（层流、紊流光滑管区、紊流过渡管区、紊流粗糙管区）。提供了2个简化计算程序，其目的是：在部分条件（如压力、重度、动力粘度、温度…等）不变的情况下，加快多次计算中的进度。

The computer computing formulas for engineering fluid mechanics are offered. With them we can fast and accurately calculate press loss, friction press loss factor, flow speed and Leino value in pipe, or pipe diameter, or friction press loss factor in turbulence interim region, and point out the flowing property of fluid (laminar flow smooth pipe region, turbulence smooth pipe region, turbulence interim pipe region, turbulence rough pipe region). Besides two simplified programs are offered to speed up the multi-calculation under the condition of some parameters keeping fixed.
