Here is a table showing the density of water in pounds per cubic foot (lb/ft³) at various temperatures: Temperature (☏) The density of water in pounds per gallon is approximately 8.34 lb/gal at STP. The density of water in pounds per cubic foot is approximately 62.4 lb/ft³ at standard temperature and pressure (STP), which is defined as 68☏ and 1 atmosphere (atm) of pressure. The density of water can also be expressed in pounds per cubic foot (lb/ft³) or pounds per gallon (lb/gal), which are common English units of measurement. In this post, we’ll explore the density of water in English units, including its definition, measurement, and various applications. For water, this property is often expressed in terms of pounds per cubic foot (lb/ft³) or pounds per gallon (lb/gal), which are the common English units of measurement. Thanks Again to and all for your help! I'm better now as a result.Sure, here’s a blog post about the density of water in English units:ĭensity is a physical property of matter that describes the amount of mass per unit volume of a substance. So now my calculation looks like this, where I have added the extra steps just to make it clear I'm playing fair with my units:

(It also helps that it looks like these calculations were performed in Mathcad.) This was for a huge system in a fast river, so the values are quite high, but they handled specific weight and density correctly: Reading both of your posts made me question everything, so then I dug deeper into previous calculations done for our machines, and found this calculation, done by a structural engineering consultant. This was for a larger machine in a slightly faster flow, but I thought my values had to be in this ball park. You are exactly correct, in that I was looking at a hand calc example from my predecessor, and I was taking it as gospel, when in fact he was confusing specific weight and density. I hope this Thank You very much for your input, and sorry for the delay - I'm just super busy, trying to get this report completed for a project submittal. Yes - I wish the US would just drop this terrible unit system once and for all! The correct drag force should be about 30 lbf. Recall the numeric value of 1 pound of mass weighs (has a force of) 1 pound and is only valid in earth's gravity.

The mass density of water is 62.4 pounds mass/ft^2. If you simply change the gamma unit tag in example #2 from "lbf" to "lb", you will get the correct result. Update - the equation you used for the drag force requires a mass density, not weight density.the Mathcad Prime result supports this. I've used this approach many times with great success. Rumor has it Prime 7 will have some controls.maybe a simple drop-down like we have in v15. You will need to standardize on a "density" unit and account for gravity, or not, in your equation.Īlternatively, if you use Mathcad 15, you could create a drop-down unit choice and use an "If" statement to set the equation up to handle the units based on user selection. As you know, a "slug" is a different unit from a "lbf", so you can't use the same equation for both and expect consistent units for a result.
