How are you today?
EX08-2 6/11/2019
Computational Fluid Dynamics (CFD) is used for analyzing how fluids in a system flow. We want to utilize CFD in this class.
EX08-1 6/11/2019
The capillary effect in a tube
Using the info on the whiteboard, make a graph of the diameter of tube vs Water and mercury heights. Print out and submit it.

How was the EX7? Is it simple or complicated?
EX07 6/10/2019
Hi Class,
This is EX07
https://drive.google.com/file/d/1D17WwbpNO5-W01fWc4Gdwwra_vl2IIAL/view?usp=sharing
You can take the EX at home, so you don’t have to come to school today. But if you want to come to school, please use the club room, computer lab on the 2nd floor, library in Namm, if V511 is not open yet.
Submit all work to me ( send email to mnakamura@citytech.cuny.edu ) or leave it in my mailbox located in Mech Dept office by 5:00pm today.
Good luck!
Dr. Masa Nakamura

Hi class
How are you today? Did you enjoy the weekend?
As I discussed, we don’t have a lecture today. Instead, we will have only an exercise (EX7). I will put the EX in openlab around 2:30 today.

Today is Friday. What is your weekend plan? We will discuss the Reynolds number more today. Are you ready?
EX06 6/7/2019
Example – Calculating Reynolds Number
A Newtonian fluid with a dynamic or absolute viscosity of 0.38 Ns/m2 and a specific gravity of 0.91 flows through a 25 mm diameter pipe with a velocity of 2.6 m/s.
The density can be calculated using the specific gravity like
ρ = 0.91 (1000 kg/m3)
= 910 kg/m3
The Reynolds Number can then be calculated using equation (1) like
Re = (910 kg/m3) (2.6 m/s) (25 mm) (10-3 m/mm) / (0.38 Ns/m2)
= 156 (kg m / s2)/N
= 156 ~ Laminar flow
(1 N = 1 kg m / s2)

Do you have any questions about the lectures? So far so good? How’s your Matlab skill? You started to remember it?
