Reverse air lift pumping can be established by injecting gas into a column of liquid; the subsequently decreased density of the gas-liquid mixture allows atmospheric pressure outside the lift conduit to establish flow. The rate of flow can be controlled by varying the gas to liquid ratio. The first lifting calculation method
If the lift has been classified as a pre-engineered lift, then additional criteria must be met prior to operation. If determined to be a critical lift, Facilities & Operations riggers or an approved contractor must be used. Once the lift has been classified and determined to be an ordinary or incidental lift, useAviation Calculation Tools - Helicopter Calculations lifting calculation methodBelow, we will demonstrate a method to calculate the theoretical thrust that that a propeller or rotor can generate. Of course in a helicopter, the rotor disk is oriented such that we call its force lift rather than thrust, thrust would be used in the case of an airplane.A Step-by-Step Guide to the WISHA Lifting CalculatorHere are some quick explanations and guidelines that you can use to gather the needed measurements for the WISHA Lifting Calculator: 1) Weight Determine the actual Weight of the object being lifted.
