Question

Octane (density=44.1 lbm/ft³) flows downward in a tube (inside diameter=0.7 in) at a mass flow rate of 5.83 lbm/min. At a certain location, the pressure is known to be 1.60 psig. Just below that point, the diameter of tube is reduced. In the reduced section 3 in below the original location, the measured pressure is 1.65 psig. What is the reduced diameter? All values of a can be assumed to equal 1.0, and friction can be ignored.

Step 1

First, let's convert the given values to consistent units. We'll convert the octane density from lbm/ft³ to lbm/in³ and the mass flow rate from lbm/min to lbm/s. Octane density = 44.1 lbm/ft³ = 44.1 lbm/ft³ * (1 ft³/12 in³) = 3.675 lbm/in³ Mass flow rate = 5.83 Show more…

Octane density = 44.1 lbm/ftÂ³ flows downward in a tube with an inside diameter of 0.7 in at a mass flow rate of 5.83 lbm/min. At a certain location, the pressure is known to be 1.60 psig. Just below that point, the diameter of the tube is reduced. In the reduced section, 3 in below the original location, the measured pressure is 1.65 psig. What is the reduced diameter? All values of a can be assumed to equal 1.0, and friction can be ignored.
