E is the actual energy delivered by the hammer per blow in Newton meters (foot pounds). S is the average net penetration in mm (inches) per blow for last five blows after the pile has been driven to a depth where successive blows have produced approximately equal net penetration for a minimum distance of last 75 mm (3 feet).

d= density of air in pounds per cubic foot ( .075 pounds per cubic foot at standard conditions ) This represents the highest speed of the air in the flow path, at or near the section of minimum area (i.e. through the valve seat at low values of L/D, through the pushrod pinch, or minimum intake cross section, which ever is smaller).

5. A story in the August 24, 2004 edition of the LA Times had the following statement: “Science geek alert: The 7.62 round has a muzzle velocity of 2,750 feet per second and imparts to the 150-grain projectile a kinetic energy of about 2,511 foot-pounds.” Check this statement. Remember the conversion factor that 1 lbf = 32.174 lbm∙ft/s2.

Students know how to calculate kinetic energy using the formula E= 1/2mv2. ... The British unit of work is the foot pound and Watt’s measurements suggested that the average horse could lift 550 pounds one foot per second. Today the definition of the horsepower is 550 ft lbs/sec and this equals 756 watts (or about ¾ kilowatt).
