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 do I calculate pump needs? Add the pumping lift andfriction losstogether. The vertical distance water needs to travel plus the friction losses from the pipe make the "total dynamic head" or TDH. This is the total pressure load the pump needs to overcome. Example: TDH = vertical distanc...

Q: "What to do if a hard drive has overheated?"The problems of overheating in hard drives are commonly related to the lack of dissipation, hard drives use magnetic fields generated by a slider (head) on an aluminum disk, in this way the information is written and read. The aluminum ...
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...
How did we calculate? Are serrated washers effective against bolt loosening? Serrated lock washers increase the friction between the bolt head/nut and the mating surface. They do this by gripping into the mating surfaces. Serrated lock washers are installed between the bolt head/nut and the matin...
The pump flow rate calculation is an essential aspect of many engineering projects. Accurate calculations ensure the efficiency, reliability, and effectiveness of your systems — from simple water pumps to complex industrial processes. The basic formula to calculate the pump flow rate is: ...
pulled it, in a never-ending cycle. In the real world, the spring would not be ideal and its material would eventually lose its elasticity, but more importantly, friction in reality is unavoidable; its net force soon reduces the magnitude of the oscillations, and the block returns to rest....
Water creates pressure or resistance, at predictable rates, so we can calculate pump head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. (A pump characteristic curve calculator might offer ...
