Can I calculate flow in a trapezoidal channel with different sideslopes?
HYDRAtools does not currently support this but it is on our revision list. You can compute a reasonable approximation by averaging the side slopes for preliminary work. For a final computation, calculate area and perimeter and verify using the Generic option. • Why am I getting an error when solving for depth of flow in an 8″ pipe? Version 2.00 was unable to solve for “d” with a small pipe (less than 12″). You can enter a guess for “d” and solve for “Q”. This has been fixed in Version 2.01. • In PIPE CALC I seem to be getting incorrect results and the area appears to be wrong. Exit out of HYDRAtools and see if “RAD” appears in the upper left corner of your display. This indicates your calculator is in Radians mode. If “RAD” is shown in the display press the RAD key (located on Left-Shift MTH on an HP48GX). Student Cogo • Can I transfer data from Student Cogo to my PC? The short answer is ‘no’.
