Frequently Asked Questions

What does this calculator calculate?

The Hydraulic Elevator Pump Power and Round-Trip Time Sizer Calculator estimates Required Pump Power based on the input parameters you provide

Why is rated load mass important in this calculation?

rated load mass is directly proportional to required pump power. When you enter rated load mass in kg, the calculator uses it in the engineering formula to compute the output

How should I interpret the result required pump power?

The calculator outputs required pump power in W. For larger power values, divide by 1000 to express the result in kW, or by 745.7 for horsepower. The result is computed directly from the input values using the defined engineering formula

What units should I use for the inputs?

Enter each value in the units shown next to the input field: Rated Load Mass (kg), Lift Height (m), Target Cycle Time (s), Gravitational Acceleration (m/s^2). Make sure all inputs use the specified units for consistent results

What assumptions does this calculator use?

This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
