AI Thread Summary
The plot in question likely illustrates mass transfer dynamics within a boundary layer, specifically in relation to flow over a flat plate. It involves the introduction of mass through a porous plate, which affects the overall mass transfer characteristics. The citation provided refers to a study by Hartnett and Eckert from 1957, which may offer foundational insights into the topic. Understanding the interaction between the flow and the porous medium is crucial for interpreting the plot accurately. This analysis is essential for grasping the principles of mass transfer in fluid dynamics.

Homework Statement


I was given a plot and a citation, but not too much clarification on what it represents. I believe it is describing mass transfer in a boundary layer.

I think it represents mass transfer in flow past a flat plate in which mass is also being introduced by flow through the porous plate.
 
Thread 'Have I solved this structural engineering equation correctly?'
Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
