Transport Phenomena Data: table, graphs. mathematics and equations. Useful for engineering students and professionals. Always have your dimensionless relations, math and graphs with you! Conversion from all kind of units to SI-units and vice versa. Numerical solution of conduction of heat and diffusion of mass into a slab, a cylinder or a sphere: the app computes the time required for a change in the mean or center temperature, or it computes those temperatures after a specified time interval. With the app you can compute the terminal velocity of any sphere in any fluid. Moreover, the pressure drop over a straight pipe is computed for a given fluid velocity of, reversed, for a given pressure drop the velocity is computed.
