Answer: The efficiency can be found using the formula: η = 0.40 x 100%. η = 40%. The efficiency of the hammer strike was 40%. Vibrations and heating of the nail are two possible reasons for the energy loss. 2) A particular chemical process has an energy efficiency of only 3.00%. To complete this large-scale chemical process, 140,000 J of

Crushing is done in three stages, reducing to 80% passing 2 cm (3/4 inch). Rod and ball mills take the ore down to an 80% passing size of 60 microns (270 mesh). METHODOLOGY The Bond equation is a useful tool to compare predicted and actual values of energy requirements for each step in taconite comminution. Crushing and grinding energy are measured

Mar 01, 2009· Crushing Strength Equations for Pipe tbird92 (Mechanical) (OP) 24 Feb 09 16:54. I am trying to find the right equations to calculate the crushing strenght, or the forces that will cause a pipe to fail, or buckle under a 2 point load. Example: imagine a pipe in a v. What force will fail buckle it

The efficiency of a riveted joint is equal to the strength of the joint divided by the strength of the un riveted plate, expressed as a percentage. Resistance to shearing one rivet: R s = π d 2 S s / 4. Resistance to tearing plate between rivets: R t = ( p D) t S t. Resistance to crushing rivet or plate: R c

Efficiency = TPH of Undersize in feed which actually passes TPH of Undersize in feed (should pass) = 469 TPH (469 22 TPH) = 95.3% Calculate the efficiency of the 1” cut on the top deck. Calculating Screen Efficiency Example

Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency

This equation, named for its authors, was presented in an SAE in 1987 (3). The equation is: Eq. 2 Where V = EBS in ft/sec; D = maximum crush in ft.; W = vehicle weight in lbs. ; DE = the increase or decrease in energy absorbed in crushing the vehicle due to impacting the pole, relative to that absorbed in an impact with a class 4-40 pole.

The efficiency calculated by the combustion analyzer is a modified equation that considers combustion efficiency and stack losses. It is a part thermal, part combustion efficiency calculation. The equation is a reasonable estimation of the steady state operating efficiency of the appliance. This is true of all analyzers currently manufactured. [1]
