How to calculate the efficiency of your data centre
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...
Machine availability is one of three KPIs used to determine Overall Equipment Effectiveness (OEE). The other two KPIs are performance and quality, which we'll discuss below. Each KPI has its own formula and helps manufacturers understand the efficiency of their operation while identifying processes ...
How to calculate motor efficiency for variable-speed centrifugal pumps: knowing the efficiencies of the pump, VSD, and motor will enable the engineer to calculate the kW input for a pump, from minimum to maximum flow and head conditions for that pump. Here, the author goes through that ...
The expression in parentheses,k2/KM, is known as the specificity constant_,_ also called the kinetic efficiency. After all of this pesky algebra, you finally have an expression that assesses the catalytic efficiency, or enzyme efficiency, of a given reaction. You can calculate the constant direc...
To evaluate the performance of an existing compressor, the objective is to calculate the compressor efficiency (η) and power requirement. Known and measured properties are: a.Standard condition gas volume flow rate (qS) or gas mass rate () ...
Businesses use the cost per lead model to track exactly how much they’re spending to bring in leads. Without that information, they can’t know the efficiency of their marketing activity, so they can’t notice when marketing performance is failing. ...
Knowing the crane capacity is critical for safely operating a crane without lowering the load or damaging the machine. This number must be recalculated each time a crane is used since it varies depending on the location of the hoist and the lift radius, among other factors. Crane load ...
In this article, we will discuss how to calculate algorithm efficiency, focusing on two main ways to measure it and providing an overview of the calculation process. What is Algorithmic Efficiency, and Why is it Important? Algorithm efficiency relates to how many resources a computer needs to ex...
To calculate ROI, the benefit (or return) of an investment is divided by the cost of the investment. The result is expressed as a percentage or aratio. Key Takeaways Return on Investment (ROI) is a popular profitability metric used to evaluate how well an investment has performed. ...
