The question is incomplete. The complete question is :
The pressure difference, Δp, ac
ross a partial blockage in an artery (called a stenosis) is approximated by the equation :
Where V is the blood velocity, μ the blood viscosity {FT/L2}, ρ the blood density {M/L3}, D the artery diameter, 
the area of the unobstructed artery, and A1 the area of the stenosis. Determine the dimensions of the constants 
and . Would this equation be valid in any system of units?
Solution :
From the dimension homogeneity, we require :
Here, x means dimension of x. i.e.
![$[ML^{-1}T^{-2}]=\frac{[K_v][ML^{-1}T^{-1}][LT^{-1}]}{[L]}+[K_u][1][ML^{-3}][L^2T^{-2}]$](https://tex.z-dn.net/?f=%24%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%3D%5Cfrac%7B%5BK_v%5D%5BML%5E%7B-1%7DT%5E%7B-1%7D%5D%5BLT%5E%7B-1%7D%5D%7D%7B%5BL%5D%7D%2B%5BK_u%5D%5B1%5D%5BML%5E%7B-3%7D%5D%5BL%5E2T%5E%7B-2%7D%5D%24)
![$=[K_v][ML^{-1}T^{-2}]+[K_u][ML^{-1}T^{-2}]$](https://tex.z-dn.net/?f=%24%3D%5BK_v%5D%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%2B%5BK_u%5D%5BML%5E%7B-1%7DT%5E%7B-2%7D%5D%24)
So, ![$[K_u]=[K_v]=[1 ]=$](https://tex.z-dn.net/?f=%24%5BK_u%5D%3D%5BK_v%5D%3D%5B1%20%5D%3D%24)
dimensionless
So, and are dimensionless constants.
This equation will be working in any system of units. The constants and will be different for different system of units.
Hello!
I'm unfamiliar with the book you are reading,
However, based on textual evidence, I think your answer relies somewhere in answer choice A or D.
I hope this helps!
He has a mass of 56 kg.
The equation given is PE = mgh.
PE = 4620 J
h = 8.4
g = 9.8
Therefore:
4620 = 82.32m
m = 4620/82.32
m = 56 (rounded to two significant digits)
Answer:
Explanation:
Given data
Required
Partial pressure of helium
Solution
First calculate the total volume of gas mixture once the stopcock is opened
So
As temperature remains constant,by Boyle's Law we calculate the partial pressure of the helium gas
So
