Power output

AI Thread Summary

In the discussion on MHD power generation, the focus is on the impact of using a metal tube for an ionized flow compared to open flow. The key question is whether the confinement of the flow within a metal tube affects the power output generated. Factors such as the interaction between the ionized flow and the tube's material, as well as potential changes in magnetic fields, are considered. The consensus leans towards the idea that the tube could influence the efficiency and output due to these interactions. Ultimately, the scenario suggests that the environment and containment method can significantly affect MHD power generation outcomes.

TL;DR Summary: If ionized flow is used to generate power/electricity by MHD method, will there be in any difference in power output if the flow is confined inside a tube made of metal instead of a free flow.

First, I want to put forward an imaginary scenario where an ionized flow is being used to generate power/electricity by MHD power generation method. The temperature of the ionized flow is the same as the surrounding atmosphere. Power/electricity is generated as the flow is ionized. Now, if the flow passes through a tube made up of metal instead of flowing in open, I want to know whether there will be any difference in power output in such a case or it will be the same?

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
