An important attribute of enzymes is their specificity. Enzymes, generally speaking, serve to catalyze only one of the hundreds of biochemical metabolic reactions that are unfold within the human body at all times. Thus a given enzyme may be thought of as a lock, and the specific compound on ...
How efficient is `efficiency'? Many people calculate the thermal efficiency of a cogeneration plant in a way that is specifically excluded by the Second Law of Thermodynamics. More useful methods account for the higher value of electricity--which can ...
The formula to calculatework efficiencyis the ratio ofoutputtoinputexpressed as a percentage. For a machine, you can determine the work put into the machine depending on how the machine works. You can generally calculate work by multiplying the force times distance for the motion. Make sure you...
To calculate most of these metrics, you need two numbers (the before and after number), and a simple percentage change formula. No matter what industry you work in, measuring your achievements in percentages provides a clear measure of growth, efficiency, or achievement. How to calculate a per...
To understand this, you need to understand the basic process of an internal-combustion engine. Here's what happens as the engine goes through its cycle: Intake stroke - The piston starts at the top, the intake valve opens and the piston moves downward to let air and gasoline into the cyli...
How does a Carnot engine work? A Carnot engine works by taking in heat from a high-temperature reservoir, converting some of it into work, and then releasing the remaining heat to a low-temperature reservoir. This process is repeated in a cycle, and the efficiency of the engine is ...
This is an equation commonly used in the manufacturing industry to monitor and improve output. A higher ratio indicates a greater efficiency in managing your assets. Turnover of Receivables Another type of cost efficiency ratio formula is used to calculate the turnover of receivables. This shows...
Financial analysts use several proven methods to calculate intrinsic value, including dividend discount models, discounted cash flow analysis, and residual income approaches. The accuracy of intrinsic value calculations depends heavily on the quality of data and assumptions you use. ...
How to Calculate Profit Margin in Excel You may find it easier to calculate your gross profit margin using computer software. One of the most common ones on the market is Microsoft Excel. Using spreadsheets can make things a little easier. Before you sit down at the computer to calculate you...
