Rear Wheel HP is assuming 10% drivetrain loss. Weight is as the car sits on the line: driver and gas in it. The answers will be for at sea level and standard pressure/temperature.
6 dni temu · This calculator uses the Motorsports Standard Atmosphere (MSA). (Not ISA - International Standard Atmosphere) Grains - Grains of water vapor per pound of dry air. The HP Correction is a better determination of ET than the DA (Density Altitude). I have included them for your benefit.
Wallace Racing - ET/MPH/HP Calculator for Quarter Mile Runs. Weight is as the car sits on the line: driver and gas in it. HP is at the crank. The answers below will be for at sea level and standard pressure/temperature. (no weather correction).
11 sie 2005 · So if you only have an 1/8 mile track to measure performance you can convert your 1/8 mile trap speed to a 1/4 mile value and then estimate the horsepower required to have achieved that 1/8 mile performance. The formulas are: Estimated RWHP for 1/4 mile = (MPH/234)^3*Weight Estimated RWHP for 1/8 mile = (MPH*1.27/234)^3*Weight
3 paź 2024 · The formula for calculating Water Horsepower is given by: \ [ \text {WHP} = \frac {QH} {3960} \] Where: WHP is the Water Horsepower, Q is the Flow Rate or Discharge in gallons per minute (gpm), H is the Total Head in feet.
28 lip 2021 · This calculator calculates the water horsepower (whp) using flow rate or discharge (q), total head (h) values.
11 sty 2017 · Huntington also determined a formula for 1/4-mile elapsed time. His formulas (slightly rearranged) are: MPH = 224 (hp/weight) 1/3 and ET = 6.290 (weight/hp) 1/3, where "MPH" is the terminal speed (trap speed), "ET" is the elapsed time, "224" is the empirically determined coefficient that includes the necessary unit conversion factors,
