How to Calculate and Solve for Standing Bubble Point Parameter | The Calculator Encyclopedia

The image above represents standing bubble point parameter.

To compute for the standing bubble point parameter, two essential parameters are needed and these parameters are API Gravity (°API) and Temperature (°Rankine) (T).

The formula for calculating standing bubble point parameter:

a = [0.00091(T – 460)] – [0.0125(°API)]

Where:

a = Standing Bubble Point Parameter, a
°API = API Gravity
T = Temperature (°Rankine)

Let’s solve an example;
Find the standing bubble point parameter when API Gravity is 32 and the temperature is 146.

This implies that:

°API = API Gravity = 32
T = Temperature (°Rankine) = 146

a = [0.00091(T – 460)] – [0.0125(°API)]
a = [0.00091(146 – 460)] – [0.0125(32)]
a = [0.00091(-314)] – [0.0125(32)]
a = [-0.28574] – [0.0125(32)]
a = [-0.28574] – [0.4]
a = -0.68574

Therefore, the standing bubble point parameter, a is -0.68574.
