Example 1.3: A cylindrical core having a radius 2.54 102 [m] and length of 0.3 [m], was flooded with brine at a steady rate of 1.100 [m³s¹], the differential pressure across the core was 10 [bar]. Calculate the absolute permeability of the core. Assume brine viscosity 0.001 [Pa.s].
An ideal gas flows through a horizontal tube at steady state. No heat is added, and no shaft work is done. The cross-sectional area of the tube changes with length and this causes the velocity to change. (a) Derive an equation relating the temperature to the velocity of the gas.(b) If nitrogen at 150 [°C] flows past one section of the tube at the velocity of 2.5 [m/s], what is the temperature at another section where its velocity is 50 [m/s]? Let Cp = 7/2R.
