How to size a Circulator Pump. Taco pump curves.

All circulator pumps are typically sized based on the heat load and head loss (pressure drop) for a given zone. Knowing the heat load (in BTU's) for a given zone, allows to calculate the required circulator pump's flow rate in gallons per minute (GPM). The next step is to calculate the head loss, or

Volume III: Failures in Pressure Vessels | Boardman LLC

A boiler stay is an internal structural element used inside boilers. Where the shell of a boiler or other pressure vessel is made of cylindrical or (part) spherical elements, the internal pressure will be contained without distortion. However, flat surfaces of any significant size will distort under pressure, tending to
