Calculate the volume of water a drum can take The drum is 80cm diametre by 1.2m height?

Why does water escape from wet clothing in a spinning clothes dryer?

Centrifugal force - the spinning motion sends everything in the drum as far from the centre of rotation as possible. The side of the drum stops the clothes, the holes in the drum let the water through.

What is the buoyancy of a 55 gallon drum?

A 30 gallon drum, of course, holds 30 gallons. This means that in order to sink this barrel in water you would have to displace 30 gallons of water. (move the water out of the way to make room for this drum) Each gallon of fresh water weighs 8.34 pounds. So if you were to totally sink this sealed drum in fresh water it would take 250.2 pounds of weight to do so. If you were to use these barrels for a pontoon boat or the like, I would suggest that you only use the barrels to a submersion level of 50%. This gives you some fudge-factor for weight distribution and walking around without having that "sinking" feeling. In salt water, you have to know the composition of the salt water, or the ratio of salt to water. Roughly, salt water weighs 64 lbs/cu. ft., as opposed to fresh water, which is about 62.2 lbs/cu. ft. There are 7.48 gallons in a cubic foot. So a gallon of salt water weighs 8.556 lbs. This means that in order to sink the drum you would have to displace more weight because salt water is heavier than fresh water which in turn will make your drum more buoyant. It would take 256.7 pounds to totally sink your drum in salt water. Keep in mind that a 30 gallon steel drum weighs between 30 and 40 pounds depending on the thickness of the steel when it was manufactured. This weight will need to be deducted from the total buoyancy. Of course plastic drums weigh less so do your math accordingly. In fresh water minus the steel drum weight of 35 pounds: 100% sinking = 215.2 lbs per drum 75% sinking = 161.4 lbs per drum 50% sinking = 107.6 lbs per drum In salt water minus the steel drum weight of 35 pounds: 100% sinking = 221.7 lbs per drum 75% sinking = 166.3 lbs per drum 50% sinking = 110.9 lbs per drum


What is function of drum in thermal power plant?

Steam drums are used on recirculating boilers that operate at subcritical pressures. The primary purpose of the steam drum is to separate the saturated steam from the steam-water mixture that leaves the heat transfer surfaces and enters the drum.
