3 dni temu · Calculation Formula. The formula to calculate revolutions per mile involves the wheel or tire's diameter and uses the relationship between the circumference of the wheel and the distance traveled in one revolution: \[ \text{Revolutions Per Mile} = \frac{63360}{\pi \times \text{Diameter (inches)}} \] where: The diameter is in inches,
5 dni temu · To calculate the radar horizon, take the height of the radar system h, and feed it into the equation: d=√(2 × Rₑ × h), where: Rₑ is the Earth's radius; and; d is the radar horizon. To consider atmospheric refraction, you must multiply the expression under the square root by an additional factor of 4/3.
6 dni temu · Calculation Formula. The calculation depends on the lower heating value of the fuel (QL) and differs for gas fuels with QL values in specific ranges: For QL < 10455 kJ/ (standard)m³: \ [ VO = 0.209 \times \frac {QL} {1000} \] For QL > 14637 kJ/ (standard)m³: \ [ VO = 0.260 \times \frac {QL} {1000} - 0.25 \] Example Calculation.
3 dni temu · Here’s a formula you can use to calculate ACH: ACH = CFM x 60 / Area x height CFM (cubic feet per minute) denotes air volume per minute, and to calculate air changes/hour, we have translated it into hours, hence multiplying by 60.
2 dni temu · Calculation Formula. Air volume is calculated using the formula: \[ \text{Air Volume (ft³)} = \text{Volumetric Air Flow (CFM)} \times \text{Total Time (Minutes)} \] Example Calculation. For instance, if an HVAC system has a volumetric air flow of 500 CFM and it operates for 60 minutes:
