Hello All,
I would like to know how to calculate the boundary layer thickness for a flow through pipes (internal flow). I can find a lot of information of boundary layer thickness for flow over flat plate, but not for internal flow. Any help is appreciated
Thanks
Hi,
I am interested in calculating the pressure drop across rectangular cylinder. I know the coefficient of drag of the cylinder from the Cd vs Re plot and the drag force across the cylinder is given by
Fd = Cd * 0.5 * rho * V^2 * frontal area.
How do i calculate the pressure drop from the...
Hi,
I have a question in calculating Nusselt and friction factor for flow in pipes. The flow in a pipe could be hydrodynamically developing, hydrodynamically fully developed, thermally developing and simultaneously developing and these four scenarios can occur for laminar and turbulent flow...
Hi,
I would like to know if choked flow can occur in a valve even if the velocity of air passing through the valve has not reached Mach 1.
Also how will I determine is the flow is choked or not, given I know the upstream and downstream pressures.
Thank you
Hi,
I would like to know what equations are used to calculate thermodynamic properties like enthalpy, Cp, entropy at a given temperature and pressure. I know i can use standard tables for these values, but I am curious as to how these are calculated. I am looking for equations in which i can...
