![]() Steam causes that signature whistle that lets one know, tea is ready. ![]() This interaction is not high-tech or complicated, and we usually take it for granted. The Mythbusters used steam at a much higher temperature than the boiling point however, our daily interaction with steam happens at 100 ☌ and 1 atm, where it has a density of 0.6 kg/m 3. The television show Mythbusters created a steam cannon, and while it was less than powerful, it was a successful proof of concept. Example: Calculate the seawater density if its salinity is 35. Higher differences in density will cause a turbine to spin faster, and in turn be more powerful. This salt water density calculator determines the density of salt water with salinities between 0 and 43 ppt, temperatures between 2 and 40° and pressures between bar, the last number being the pressure at a depth of 10 km or 6.21 miles. This is where the density of steam comes in handy. The turbine spins a generator which makes electric current. Today, perhaps even more importantly steam is used in the production of electricity Nuclear power heats water into steam which rotates a turbine. Smaller steam engines were used in factories and helped ramp up production. In 1912, steam drove the Titanic, and is still used to power ships today. With the invention and refinement of the steam engine many possibilities were created. Steam was the footing of the Industrial Revolution. Water, while remarkable in its liquid form, becomes immensely more useful as a gas. "Thus according to the latter observers, the density at 100 is 0.0006187 ." Volume of solid body inside water V V 4 3 V 4 Weight of water displaced by immersed portion of the body 3 V 4 × 10 3 × g By the principle of floatation, V d g 3 V 4 × 10 3 g d 3 4 × 10 3 750 k g m 3. ![]() "Then the density estimate follows from the perfect gas law. Let V be the volume and d be the density of the solid then weight of the body V d g. The density of water is 10 3 kg/m 3, and the density of steam is 0.6 kg/m 3." "At 100 ℃ and atmospheric pressure the heat of vaporization of steam is 2260 kJ/kg, "If the entire 3 L of water were vaporized, the density of the steam would beīeiser, Arthur. ![]()
