Thank you! So Breakdown voltage, IMax and Rds-on are the key parameters I should look for?

This one is the actual part in question.

I am currently in need of a MOSFET to replace the AUIRLR2908 I am currently using. This power MOSFET is used in enhancement mode for switching. The data sheet is attached for reference. What are some of the key parametrics I should be concerned with when trying to find a drop in equivalent...

Let's say the container is being pressurized at 2psi a second. I want to decrease the pressure of the system by 2psi at any point in time in a reproducible way. Does this make sense?

Greetings, I have an experiment that pressurizes a small volume at variable rates. 1, 2, and 3 psi/sec. I am trying to think of a way to reproducibly drop the pressure of the container by a known amount while it is being pressurized. Are there valves for this type of experiment? What are...

You get to choose the flow rate/velocity and the dimensions of the problem are set for you. I chose 2gal/min as a nominal value. I'd like to solve the problem as accurately and precisely as possible. Thanks!

Here is my work. I assumed 3 regions. 1=before the orifice 2=in the orifice 3=after the orifice. The fluid is water. I broke the problem up into 2 parts. Part 1: Transition between region 1 and 2 Part 2: Transition between 2 and 3. I chose diameter of 1in in regions 1 and 3 and a diameter...

Greetings, I am trying to understand how to setup/solve for the pressure drop across an orifice L=3.5in The pipe diameter starts at 1in, then abruptly decreases to 0.5in for the length of the orifice, and abruptly transitions to 1in diameter. (See the attached file for an illustration.)...

Thank you very much for your reply. But I wonder what the H stands for? I think your equation determines the pressure drop due to a change in potential energy. Unfortunately, my system is perfectly horizontal, or I can assume Delta H is zero, so I have no losses due to potential energy...

Greetings, I have very little experience with fluid dynamics and I was wondering how I can calculate a pressure drop across an abrupt change in diameter of the piping used for water. Any help is appreciated! Thanks!

Thank you for helping me clear this up! Much appreciated!

Gene, In my problem, I stated AC current. The current waveform is modeled by a sinewave, so half the time it is in the positive z axis and half the time it is in the negative z axis. I guess, I don't understand why you wouldn't just integrate in cylindrical units as opposed to cartesian...

I will try stokes theorem! Thank you for your help!

Here is a diagram of the coordinate system I used. Theta starts at the positive x-axis and rotates towards the positive y axis. r = rho , which is the distance away from the z axis.

Gene, Please see this link, this is how I solved the Curl of the Magnetic Field
