Efficiency of hydraulic crane Solution

STEP 0: Pre-Calculation Summary
Formula Used
efficiency = (Weight lifted*Height through which weight lifted)/(Pressure*Area of ram*Length of stroke)
n = (W*h)/(P*A*L)
This formula uses 5 Variables
Variables Used
Weight lifted - Weight lifted is defined as the amount of weight lifted vertically by the hook of a hydraulic crane or some other equipment. (Measured in Newton)
Height through which weight lifted - Height through which weight lifted is a measure of vertical distance, either vertical extent or vertical position. (Measured in Meter)
Pressure - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. (Measured in Pascal)
Area of ram - Area of ram is defined as the area covered by the large ram in which a piston or plunger is displaced by the pressure of a fluid. (Measured in Square Meter)
Length of stroke - Length of stroke is the range of movement of piston. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Weight lifted: 50 Newton --> 50 Newton No Conversion Required
Height through which weight lifted: 50 Meter --> 50 Meter No Conversion Required
Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Area of ram: 50 Square Meter --> 50 Square Meter No Conversion Required
Length of stroke: 0.5 Meter --> 0.5 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
n = (W*h)/(P*A*L) --> (50*50)/(800*50*0.5)
Evaluating ... ...
n = 0.125
STEP 3: Convert Result to Output's Unit
0.125 --> No Conversion Required
FINAL ANSWER
0.125 <-- Efficiency

What is the principle of hydraulic crane?

Cranes, like all machines, obey the principle of conservation of energy. This means that the energy delivered to the load cannot exceed the energy put into the machine. For example, if a pulley system multiplies the applied force by ten, then the load moves only one tenth as far as the applied force.

How efficient is a hydraulic crane?

In these instances we have found that cranes are usually only working at 30% to 50% efficiency. This is highly inefficient, and it raises the cost of the project due to the cost of the cranes, plus the labour needed to erect, service, operate, and dismantle the cranes during the extent of the project.

How to Calculate Efficiency of hydraulic crane?

Efficiency of hydraulic crane calculator uses efficiency = (Weight lifted*Height through which weight lifted)/(Pressure*Area of ram*Length of stroke) to calculate the Efficiency, The Efficiency of hydraulic crane formula is defined as the ratio of output to the input of the hydraulic crane. Efficiency is denoted by n symbol.

How to calculate Efficiency of hydraulic crane using this online calculator? To use this online calculator for Efficiency of hydraulic crane, enter Weight lifted (W), Height through which weight lifted (h), Pressure (P), Area of ram (A) & Length of stroke (L) and hit the calculate button. Here is how the Efficiency of hydraulic crane calculation can be explained with given input values -> 0.125 = (50*50)/(800*50*0.5).

FAQ

What is Efficiency of hydraulic crane?
The Efficiency of hydraulic crane formula is defined as the ratio of output to the input of the hydraulic crane and is represented as n = (W*h)/(P*A*L) or efficiency = (Weight lifted*Height through which weight lifted)/(Pressure*Area of ram*Length of stroke). Weight lifted is defined as the amount of weight lifted vertically by the hook of a hydraulic crane or some other equipment, Height through which weight lifted is a measure of vertical distance, either vertical extent or vertical position, Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed, Area of ram is defined as the area covered by the large ram in which a piston or plunger is displaced by the pressure of a fluid & Length of stroke is the range of movement of piston.
How to calculate Efficiency of hydraulic crane?
The Efficiency of hydraulic crane formula is defined as the ratio of output to the input of the hydraulic crane is calculated using efficiency = (Weight lifted*Height through which weight lifted)/(Pressure*Area of ram*Length of stroke). To calculate Efficiency of hydraulic crane, you need Weight lifted (W), Height through which weight lifted (h), Pressure (P), Area of ram (A) & Length of stroke (L). With our tool, you need to enter the respective value for Weight lifted, Height through which weight lifted, Pressure, Area of ram & Length of stroke and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
How many ways are there to calculate Efficiency?
In this formula, Efficiency uses Weight lifted, Height through which weight lifted, Pressure, Area of ram & Length of stroke. We can use 7 other way(s) to calculate the same, which is/are as follows -
  • work_output = Weight lifted*Height through which weight lifted
  • power_input = Pressure*Area of ram*Length of stroke
  • efficiency = (Weight lifted*Height through which weight lifted)/(Pressure*Area of ram*Length of stroke)
  • workdone = Work done per minute*Total Time Taken
  • slip_coupling = 1-Efficiency of fluid coupling
  • Efficiency_of_fluid_coupling = Speed of shaft A in rpm/Speed of shaft B in rpm
  • slip_coupling = 1-(Speed of shaft B in rpm/Speed of shaft A in rpm)
