(Assume a density of water p 62.4 lb/ft3. Calculate the force (in Ib) on one of the ends due to hydrostatic pressure. The tank has a radius of 2 ft and is 6 ft long. Suppose the tank is halfway full of water. Meme posts made outside this time will be removed. Consider a horizontally oriented cylindrical water tank (see the figure below). Meme posts are allowed only Saturday, Sunday, and Monday. You can be an account with a website, but not a website with an account. Trolling, posts intentionally inciting conflict, personal attacks, and spam will be removed.Īvoid posting blogspam, blog self-promotion, or personally monetized links. Since the specific weight of water is given as 62.4 lb/ft3 and we know that 1 gallon is equal to 1/7.48 cubic feet, we can substitute these values into the formula: Weight of 1 gallon of water 62.4 lb/ft3 x (1/7.48 ft3) Simplifying the equation: Weight of 1 gallon of water 62.4 lb/ft3 x 0.1337 ft3. Just like in the metric system when we see. A lbf is the amount of force necessary to accelerate 1lbm at a rate of 32.2 ft/s 2. Racism, sexism or any other kind of intolerance or discrimination will not be tolerated. This stems from a misunderstanding of lbf and lbm. Most people are content to refer to the density of water as 62.4 lbs/ft3 even though it isn't formally correct. Otherwise your post may get deleted.ĭo your own research, follow basic guidelines, and be sure to google your question beforehand. We generally don't use the formal definition of density for water but assume we are on Earth and actually use its weight density which we know to be 62.4 lbs/ ft3 or 8.34 lbs/gallon. If the topic of your post is currently covered in one of the megathreads/stickied posts at the top of the page, please put your content as a comment there instead. Not reading them and then complaining will not earn you any sympathy. This is a place for engineering students of any discipline to discuss study methods, get homework help, get job search advice, and find a compassionate ear when you get a 40% on your midterm after studying all night.
