A properly designed settler or clarifier has an overflow launder to distribute the upward velocity evenly around the tank. But when a cylindrical tank is installed with a single overflow outlet, say with an outlet velocity 10X the upflow velocity, what is the magnitude of the effect on upflow...
What is the best way to estimate size of exchanger in a tank recirculation loop to heat a tank of fluid from one temperature to another in a given time using a steady (and limited) flow of heating fluid at constant supply temperature? It is unsteady state in that the process inlet to the...
Vacuum filtrate receiver pump occasionally pumps receiver empty and loses its prime when level control fails. Pump is about 10 feet below bottom of receiver. An old filter manual says that receivers can be fitted with an added connection for centrifugal pumps to prevent loss of prime. However...
Are there some rules of thumb for accuracy of estimates at various stages of engineering, like ballpark, back of envelope, preliminary engineering, detailed engineering, etc? Seems like I have seen figures from 250% going down to 10% as engineering effort is expended.
