I'm currently building a thermal controller that can manage the cooling of various types of heat exchangers, and I'm specifically working on cooling a heat exchanger for an EV fast charger. I need to decide the optimal pump and fan speeds to achieve efficient cooling, but I'm not sure about the...
I am developing a Taekwondo body protector scoring system using a textile piezoelectric sensor. The sensor is designed to detect mechanical force and convert it into an electrical charge. However, it is sensitive to temperature variations, leading to potential inaccuracies and instability in the...
TL;DR Summary: How to calculate the operational amplifiers in the circuit diagram
Hello Everyone,
I am trying to learn the circuit diagram of one of a device in which I will be doing modifications as a part of my Masters's Research to make it performance better. My background is in Mechanical...
I was searching for some science forums online yesterday, so I could join one to learn and contribute back. The Forums that operate like early 2000 ones, and their goals are more aligned toward users than creating content for monster spiders.
I am glad that I have ended up here now. I visited a...
At first, I thought that this humanoid robot was just really good CGI, but it's actually real.
The facial movements and expressions are eerily realistic and lifelike.
Hello,

Hi All,
Really struggling to get my head around what I'm doing wrong - every time my answer of wire diameter comes out too small for what's included in the table of SWG. I must be doing something wrong somewhere - my attempt is below.
Any help is very much appreciated.
