How to calculate pressure drop due to friction in a piping system--Part 2: the fundamentals of pumped water systems.(Tech Topics)Pelikan, Bob
Define the head loss application. In this example, a water pump in the basement of a 10-story building supplies domestic water to every floor. Assuming that each floor in the building represents 12 feet of height, you can calculate the head loss due to elevation and subtract it from the p...
How to calculate NPS NPS is calculated by subtracting the percentage of customers who answer the NPS question with a 6 or lower (known as ‘detractors’) from the percentage of customers who answer with a 9 or 10 (known as ‘promoters’). ...
1. Customer Churn Rate Enables You to Calculate Lifetime Value Churn rate is a measure of a business’s current performance, but it can also be used to gain an understanding of longer-term performance. “Average customer life time” is a metric that can be extrapolated from churn, and it...
Staying active can improve your well-being and aid in weight loss. However, factors likeheat, humidity, and friction from clothing can trigger breakouts.Here are some tips for exercising wisely: Opt for indoor workouts in air-conditioned environments. ...
Compared to user retention rates, churn rates are easy to calculate. You just use the following formula: Customer Churn Rate = (C / S) x 100 In this formula, C is the number of churned users and S is the number of users at the start of the month. Let’s plug in the numbers we...
Add all the fittings and the pipe length to compute the total friction loss in feet of head -- this will be the Friction Head. Each pipe fitting is equivalent to a certain length of pipe. Determine the type of centrifugal pump needed. As pump manufacturers build pumps for particular purpose...
A static weight test is when you take a known/calibrated weight and hang it from your power meter. For power meters that support this type of test, they’ll display a given value and allow you to calculate whether that value is correct. For a dual-sided unit, you’d want the value ...
These findings provide a conceptually different view of the evolution of sliding that, macroscopically, is generally attributed to ‘dynamic friction’ at the transition from ‘static friction’, occurring after the initial rupture. Global measurements that average over spatial and significant temporal sca...
If you are using surveys, calculate the sample size fromhere. 2. Ask for Feedback But Innovate Yourself Always listen to the customers before, during, and after product development to drive new ideas and innovation. But there is a caveat. ...
