Description

From the listing uploaded by “split-store”.

Flow Calculator is calculator of open channel flow. App calculates Manning equation for different channel shapes (user can choose different parameters of equation to be calculated). App supports rectangular, trapezoidal, triangular and circular channel shape. App also contains short theory behind Manning equation and table with values of all Manning coefficients. Manning equation is empirical equation estimating open channel flow: v = 1/n*R^(2/3)*S^(1/2) where: v...cross section average velocity (m/s) n...Manning coefficient R...hydraulic radius (m) S...slope of water surface (m/m) User can choose different parameters to be calculated for open channel flow: RECTANGULAR CHANNEL - velocity(v) & discharge(Q) - channel slope(S) from velocity(v) - channel slope(S) from discharge(Q) - manning coefficient(n) from velocity(v) - manning coefficient(n) from discharge(Q) - water depth(h) from discharge(Q) TRAPEZOIDAL CHANNEL - velocity(v) & discharge(Q) - channel slope(S) from velocity(v) - channel slope(S) from discharge(Q) - manning coefficient(n) from velocity(v) - manning coefficient(n) from discharge(Q) - water depth(h) from discharge(Q) - bank slope(m) from discharge(Q) TRIANGULAR CHANNEL - velocity(v) & discharge(Q) - channel slope(S) from velocity(v) - channel slope(S) from discharge(Q) - manning coefficient(n) from velocity(v) - manning coefficient(n) from discharge(Q) - water depth(h) from discharge(Q) - bank slope(m) from discharge(Q) CIRCULAR CHANNEL - velocity(v) & discharge(Q) - channel slope(S) from velocity(v) - channel slope(S) from discharge(Q) - manning coefficient(n) from velocity(v) - manning coefficient(n) from discharge(Q) - water depth(h) from discharge(Q)

Flow Calculator APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Flow Calculator APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 916091bc48b74c761116682dc9898051.
