Calculating shear stress in pipe flow

The shear rate for a fluid flowing between two parallel plates, one moving at a constant speed and the other one stationary (Couette flow), is defined by where: • is the shear rate, measured in reciprocal seconds; • v is the velocity of the moving plate, measured in meters per second; WebConduit tractive shear stress is now calculated when using the following solvers (versions 10.00.00.40 and later). ... The flow used by the tractive force calculation is capped at the full flow capacity of the pipe. So if the calculated flow in the conduit is higher than the capacity (i.e., if the pipe is above capacity), the tractive force ...
