Temperature Ratio at Start and End of Ramming Process Solution

STEP 0: Pre-Calculation Summary

Formula Used

Temperature Ratio = 1+(Velocity^2*(Heat Capacity Ratio-1))/(2*Heat Capacity Ratio*[R]*Initial Temperature)
T_ratio = 1+(v_process^2*(γ-1))/(2*γ*[R]*T_i)
This formula uses 1 Constants, 4 Variables

Constants Used

[R] - Universal gas constant Value Taken As 8.31446261815324

Variables Used

Temperature Ratio - Temperature Ratio is the ratio of the absolute temperature of the refrigerant at the evaporator coil to the absolute temperature of the refrigerant at the condenser coil.
Velocity - (Measured in Meter per Second) - Velocity is the speed at which air moves through the refrigeration system, affecting the cooling process and overall system performance.
Heat Capacity Ratio - Heat Capacity Ratio is the ratio of the heat capacity at constant pressure to heat capacity at constant volume in air refrigeration systems.
Initial Temperature - (Measured in Kelvin) - Initial Temperature is the temperature of air at the starting point of the refrigeration process, typically measured in degrees Celsius or Fahrenheit.

STEP 1: Convert Input(s) to Base Unit

Velocity: 60 Meter per Second --> 60 Meter per Second No Conversion Required
Heat Capacity Ratio: 1.4 --> No Conversion Required
Initial Temperature: 305 Kelvin --> 305 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_ratio = 1+(v_process^2*(γ-1))/(2*γ*[R]*T_i) --> 1+(60^2*(1.4-1))/(2*1.4*[R]*305)

Evaluating ... ...

T_ratio = 1.20280116072778

STEP 3: Convert Result to Output's Unit

1.20280116072778 --> No Conversion Required

FINAL ANSWER

1.20280116072778 ≈ 1.202801 <-- Temperature Ratio

What is Ram Air?

Ram air is the air that is compressed by the forward motion of an aircraft as it moves through the atmosphere. This dynamic pressure of the incoming air increases its pressure and temperature due to the aircraft's speed. Ram air is utilized in various aircraft systems, including ramjet engines and air cooling systems, where it helps enhance performance by providing a source of high-pressure air that can be used for combustion or cooling.
