Your process is going to have a couple of problems.
-- You'll never turn steam into ice by adding heat. That's like trying to
make a 3-ft board fit into a 2-ft space by gluing another piece onto it.
-- Without some pretty fancy pressurization equipment, it's going to be
pretty difficult to make any ice at 10° C.

for converting cubic meter to ton , density or specific volume is needed. specific volume unite is m3/kg. steam cubic meter/ (cubic meter/kg)= steam (kg ) /1000= tone of steam
First convert 1 lb of water to lb-moles which is 0.055 lb-moles (you'll need this later). This problem can be broken into 3 steps:(1) You need to detemine how much heat is needed to raise room temperature water (68oF) to 212oF. This can be used using the heat capacity of water which at room temperature is 1 Btu/lboF. So the amount of heat needed for this is:Q1 = m*Cp*ΔT= (1 lb)*(1 Btu/lboF)*(212 - 68oF)= 144 Btu(2) Next you need to account for the phase change. The water changes to steam at 212oF. You use the heat of vaporization which you can look up in any Chemistry or Chemical Engineering Handbook. The Hvap that I found is 17493.5 Btu/lb-mole.Q2 = n(lb-moles)*Hvap= (0.055 lb-moles)*(17493.5 Btu/lb-mole)= 972.64 Btu(3) Next you need to find out how much heat is needed to raise the temperature of the steam from 212 to 213oF. You can look up the heat capacity of steam at 212oF to be 0.485 Btu/lboF.Q3 = m*Cp*ΔT= (1 lb)*(0.485 Btu/lboF)*(213-212oF)= 0.485 BtuTo find the total heat needed add Q1+Q2+Q3 (144+972.64+0.485) =1117.12 Btu
It would take 1 ton of water to create 1 ton of steam.
The answer will depend on the units for the temperature.
Approximately 30,000 gallons of water is required to condense one ton of steam.
The amount of heat removed during the process of steam condensing and then freezing into ice is calculated by adding the heat required to condense the steam and the heat required to freeze the resulting water. This is determined using the specific heat capacity and latent heat of vaporization/condensation for water.
No, heating water to 100°C will not cause it to condense into steam - it will actually reach its boiling point and turn into steam. Condensation occurs when steam loses heat and converts back into water.
rise temperature, increase the insulation. Also, air does not own much mass. It will not condense the steam faster and much.
Steam has lower density and thermal capacity than water, so it does not transfer heat as efficiently. This means that steam does not heat up your hand fast enough to cause burns, while water directly transfers its heat to your skin due to its higher density and thermal capacity.
The process involves increasing the temperature of water from 8°C to 100°C and then changing its phase to steam at 100°C. The total heat energy required can be calculated using the specific heat capacity of water and the heat of vaporization. The formula Q = mcΔT can be used to find the heat energy needed, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the temperature change.
It depends on the ship in question. Steam is often used for things other than just propulsion. It is sometime used to heat a ship and to heat hot water. Nuclear and steam vessels run their power on steam.
Some of the heat is used to produce electricity, the rest is waste and put into the environment. Much of the energy of the heat is lost as the steam passes through the turbines, with the heat being converted to mechanical energy, and then to electrical. This accounts for about 35% to 40% of the energy of the heat, cooling it by the removal of that heat. It would be possible for residual heat to be tapped for conversion into electricity, also, but this is not done in most nuclear reactors. Converting it to electricity would get another 10% or so of the heat of the remaining steam, cooling the steam further. The remainder of the heat is waste. It is dumped into the environment, primarily into the air, by using heat exchangers and cooling towers. In this system, the steam is used to heat water, condensing in the process. The water is then used to heat air in the cooling tower. Another way to get rid of waste heat is to use heat exchangers to heat a nearby body of water, such as a lake, the ocean, or a river. This is usually done only in the summer, when the atmosphere is warm and the cooling towers are not efficient enough to do their work.
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
Yes, water can evaporate into steam when it reaches its boiling point. Clouds are formed when water vapor in the air condenses around particles in the atmosphere. So, technically, clouds are not evaporating, but rather forming through condensation.
That is a question that does not have one single answer. For instance, if the pressure of the steam is raised, less steam is needed. As pressure rises, temperature will also rise due to adiabatic work done on the steam. Also, higher temperatures are needed at higher pressures to make sure the steam does not condense. Raising the temperature of the steam at a given pressure also means that less steam is needed to provide the same amount of energy. Efficiency will also vary, depending on the turbine, and other factors, such ascondenser vacuum. In general, running a pressure around 40 - 45 PSI, it will take 20,000 - 25,000 pounds of steam per hour to generate one megawatt of electricity during that hour. This is with steam that is just above saturation (around 285°F). So, for 5 MW, you'd need around 100,000 pounds of steam an hour. The pipe size would depend on the turbine. A 55 MW turbine (common for geothermal), might have two pipes bringing steam in (one per side), both of which are around 30" in diameter. For 100,000 pounds of steam an hour, much smaller pipes would suffice. However, expanding and then compressing the steam repeatedly is something you want to avoid. Note that these figures reflect more of a geothermal application. The pressure and temperature of steam from a boiler will typically be much higher.
