What is the formula for calculating the density of the atmosphere at each different pressure level, assuming dry air and a value of 287 J/ Kg K? For example when : pressure level (mb) = 1000 temperature (K) = 238.18 height (m) = -20.25 density (kg/m^3) ...
This formula is to be used for calculating power when voltage V and resistance R are known to us. It is clear from equation (3) that power is inversely proportional to the resistance. Thus, the resistance of high power devices is smaller than the low power ones. For example, the resistan...
