Grady Hillhouse is a professional civil engineer and hobbyist everything else in San Antonio, Texas. Randall Munroe said, "You can look at practically any part of anything manmade around you and think, Some engineer was frustrated while designing this. It's a little human connection." My goal for Practical Engineering is to increase exposure and interest in the field of engineering. I'm trying to highlight that connection between the world around us and the energy, passion, and thought that goes into making it a nicer place to live.

How to Make Free Energy Water Pump - Ram Pump

How to make a hydraulic ram pump which requires no electricity and no motor. NOTE : This pump uses falling water to lift a lesser amount of water to a higher elevation than the source. So, being primarily used for lifting relatively small amount of water to a higher elevation. if you want to deliver 2 cubic meter of water to an elevated location, you need at least 6 cubic meters of water to operate the pump 4 cubic meters of which will be used to drive the pump and goes directly as waste.

What is Water Hammer? | DFT Inc.

Water hammer is a shock wave, transmitted through fluid contained in a piping system. It occurs when fluid in motion is suddenly forced to stop moving, and frequently occurs at pump shut down. We will be showing the difference between using a swing check valve, and a spring assisted D.F.T. Silent Check valve. Here you can see the fluid flow upon pump start up. The motion and slamming of the swing check can cause damage to sealing surfaces, and fatigue… and wear to the hinge pins. When the pump shuts down, it is gravity and reverse flow that closes or slams...

How to Collapse a Pipe by Closing a Valve

Water hammer can work in both directions, and I only discussed one of those in the previous video (https://www.youtube.com/watch?v=xoLmVFAFjn4). Today's episode revisits that demonstration to show how water hammer can form a vacuum pressure in a pipe. Momentum carrying fluid away from a valve wants to keep going even after the valve is closed. This generates a negative pressure than can cause major damage! -Patreon: http://patreon.com/PracticalEngineering -Website: http://practical.engineering This video was sponsored by Skillshare.

Groundwater Flow Demonstration Model

I was commissioned to build this model in support of a presentation about geotechnical engineering. The goal is to illustrate the flow paths that groundwater takes under an obstruction (e.g. a sheet pile or cutoff wall). So much of engineering is just theoretical work, so it was really cool to see such an elegant example of a geotechnical engineering concept borne out in real dirt and water. Thanks for watching and let me know what you think.

Surge(water hammer) Protection System

Water hammer (or, more generally, fluid hammer) is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock. This pressure wave can cause major problems, from noise and vibration to pipe collapse. It is possible to reduce the effects of the water hammer pulses with accumulators, expansion tanks and other...

Sand Castle Holds Up A Car! - Mechanically Stabilized Earth

Dirt is probably the cheapest and simplest construction material out there, but it's not very strong compared to other choices. Luckily geotechnical engineers have developed a way to strengthen earthen materials with almost no additional effort - Mechanically Stabilized Earth (aka MSE or Reinforced Soil). If you look closely, you'll see MSE walls are everywhere. Thanks for watching, and let me know what you think!

How Soil Destroys Buildings

Okay this is the last video on the hazards of soil mechanics for a while :) Support for this video comes from Brilliant: https://brilliant.org/PracticalEngineering/ Expansive soils cause more property damage per year than earthquakes, floods, hurricanes, and tornadoes combined. Expansive soils are a slow-moving geologic phenomenon, which makes them not very news-worthy. However, they still cause a tremendous amount of damage to buildings and the public infrastructure we rely on every day.
