First I'd like to say sorry if someone has. 0 Aug 2006 Main Menu Diameter (d) Liner length (L) Definitions Stroke 1Hz:= bbl 42gal:= Mud pump liner Note: A triplex mud pump has three pump liners. The term is also used in other engineering contexts, such as hydraulic pumps and electronic components. field units are used in the com- panion book, options of using U. Pick a volumetric efficiency for the rpm you are interested in. Please refer to the Appendix D for the details on how each parameter was calculated. A less dense item generally occupies more volume of space, in comparison to its actual weight. If the engine is capable of a VE of 1. Highly recommended. It takes inputs of Engine CID, number of turbos, ambient air temp, engine volumetric efficiency, and adiabatic efficiency of the turbo (typically.
