Why is a recovery period between bouts of exercise important? Active recovery prevents postexercise syncope by enhancing venous return in augmenting cardiac preload through rhythmic contractions of skeletal muscle (i.e., the muscle pump). This may be the best justification for performing a cool-down after intense exercise. Which principle of exercise is concerned with maintaining a […]
What is the stoichiometric air/fuel ratio?
What is the stoichiometric air/fuel ratio? about 14.7:1 How is stoichiometric air fuel ratio calculated? Stoichiometric air means the minimum air in stoichiometric mixture. The stoichiometric air/fuel ratio (AFR) can be calculated from the reaction equation (g/g). For gas AFR is usually determined in m3/m3. The actual combustion air depends also on the assumed air […]
What causes vortex shedding?
What causes vortex shedding? Vortex shedding happens when wind hits a structure, causing alternating vorticies to form at a certain frequency. This in turn causes the system to excite and produce a vibrational load. How do I stop my vortex from shedding? ABSTRACT: Vortex shedding of circular cylinders in uniform cross flow may be prevented […]
How is drill pipe displacement calculated?
How is drill pipe displacement calculated? Open-Ended Drill Pipe Displacement Displacement = Cross-sectional Area × Length. Sample Problem. Solution: OD = 3 in. = OD Area = 0.7854 × 0.25 ft × 0.25 ft = 0.0491 ft^2. How do you calculate tubing capacity? The formula for the volume of cylinder is: cylinder volume = π […]
What is cellular manufacturing system?
What is cellular manufacturing system? Cellular manufacturing involves the use of multiple “cells” in an assembly line fashion. Each of these cells is composed of one or multiple different machines which accomplish a certain task. The product moves from one cell to the next, each station completing part of the manufacturing process. What do you […]
How does an air preheater work?
How does an air preheater work? Air Preheaters have a shell and tube type construction where exhaust heat from the flue gases is transferred to the air when they come in indirect contact with each other. Air Preheaters consist of a shell where tubes are arranged in a square or triangular pitch and are welded […]
How does water cement ratio affect the strength of concrete?
How does water cement ratio affect the strength of concrete? The water–cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Too much water will […]
