Yes. Left unaddressed, cavitation can cause extensive damage to system components, but of course, the damage to a pump is often most obvious in the impeller. Because the impeller, and the way it interacts with system water, are so important to pump performance, cavitation is a ser...
The detected intensities from the mass spectrometer were calibrated by linear regression, and then the equation of the calibration curve was used to calculate concentrations of dissolved ions in the electrolyte. The dissolution rate of Al is converted by subtracting the solute contribution from the ...
The "Hemisphere pump problem" can be solved by using anti-cavitation devices, such as inducers or pre-swirl stators, to reduce the formation of vapor bubbles and increase pump efficiency. Another solution is to modify the shape of the pump or container to reduce the ...

By positioning ultrasonic sensors vertically, one can obtain the vertical component of wind speed. Given that wind speed comprises both velocity and direction—meaning it is a vector—we can calculate wind direction through vector composition. More simply, trigonometric functions can be employed to asc...
Step 1 – Calculate The Height Of The Transom Step 2 – Measure The Propellors Radius Step 3 – Add In A Margin The Final Measurement Remember:When calculating the shaft length, always make an allowance for the method used to mount the electric outboard motor to the transom. Some motors use...
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 ...
To calculate the equivalent resistance divide the battery’s full charge voltage by the current draw you measured above the result is the number of ohms of resistance you need to simulate your motors. Make sure the resistor you use can handle the load otherwise it will overheat and burn up....
Define cavitation What is the difference between a 'phone' and a 'phoneme'? What does it mean when atmospheric pressure is low? If a sound seems to be getting lower in pitch, what is increasing? Can you describe the manner in which people perceive communication...
Calculate input power and pumping efficiency. Analytical Modeling Build a mathematical model of the pump based on physics principles. Compare predictions to measured data to validate model accuracy. Component Changes Try different cylinder materials like steel or plastic. ...
