Here's a drawing of what I'm looking at:
When the machine is stopped, air will leak and equalize with the surrounding atmosphere (at normal temp / pressure). It can leak in any direction: the tubing is setup to take outside air in, and the hole on the top releases air back outside too, but it...
Yes sir, I have to design a controller for variable pressure control, where the differential pressure is just a few kPa (abs pressure a few kPa over local air pressure).
When you said it is going to need a major pump for a hole that big? Was it intuition? Looking over my notes again, it is specified as the max opening surface area but the size can be configured programmatically. Most users will never need an opening that big, perhaps. Say the size was 4 sq in...
Understood, it is 10 ft x 10 ft x 10 ft and needs to maintain 106,000 Pa. Maximum hole size surface area is 1 sq ft. What blower / air pump do I need to buy is the question. It won’t have heavier air — just plain air, whatever is in the environment. Thanks!
Hi Russ, thanks for your reply. The size of the container is 10 ft (~3 meters), in all directions, cubic. The hole is in one spot at the top of the container, centered. The air pump will be in one location at the bottom of the container. It's ok to have a pressure gradient within the container...
Hey all,
I've got a container that needs to maintain a certain amount of air pressure for the contents inside to develop correctly. However, it is an open container (like a big box with a hole in it), so without a pump constantly pushing air into it, it will rapidly drop pressure to equalize...
I took a quiz that I was very confident in and just got the scores back today -- I did terribly (50%). Anyway, I am trying to understand where my mistake is below. I went over this three times and I cannot figure out why it's wrong (it looks right to me).
To Prove: ~(p ∧ r) ∨ ~(q ∨ r) ≡ p ∧ r →...
You were right, it was a software bug. Ridiculous that they don't support something as important as Google Chrome (which has around 42.5% market share).
Homework Statement
Here is a small part of an EESEE data set, "Nutrition and Breakfast Cereals," that describes the nutritional content per serving of 77 brands of breakfast cereals:
What are the individuals in this data set?
For each individual, what variables are given? Which of these...
I know that you can superheat the liquid, but that's not what I'm getting at. Like phinds rephrased, why does water boil at 100 deg C at STP? (I know that intermolecular forces etc come into play, but that's not what I'm getting at.) Before anyone brings up the latent heat of vaporization etc...
