When steam condenses on the wall of an exposed/uninsulated steam pipe, it gives up its enthalpy of evaporation. Proper utilization of steam helps in saving in the input cost of water and coal. Saving of each kg of steam is directly proportional to the saving of some percentage of water, ...
Calculate the heat formation: 4NH 3 (g)+5O 2 (g)+6H 2 O(l) How to calculate the heat capacity of calorimeter when heat capacity is equal to 403 J/K and your change in temperature is equal to 2.81 degree Celsius? How are heat joules measured?
In summary, to calculate the mass of gas in a tank, first measure the volume of gas in the tank. Next, determine the gas's density, which can vary with temperature and pressure. Finally, use the formula: mass = volume × density. Ensure that all measurements are in compatible units to...
Titanium has an ''HCP'' unit cell for which the ratio of the lattice parameters c/a is 1.58. If the radius of the T_{i} atom is 0.1445 ''nm''. (a) Determine the unit cell volume (b) Calculate the density of T_{i} Integration provides a mean ...

hg = Specific enthalpy of saturated steam (total energy required to generate steam from water at 0°C (32°F)). Heating processes using steam generally use the latent heat of evaporation (Hfg) to heat the product. As seen in the table, this latent heat of evaporation is greatest at lower...
T = Saturation point of steam/water (boiling point) vf = Specific volume of saturated water (liquid). vg = Specific volume of saturated steam (gas). hf = Specific enthalpy of saturated water (energy required to heat water from 0°C (32°F) to the boiling point) ...
How to calculate enthalpy of formation At what temperature will the vapor pressure of a liquid be four times the value at 87 degrees C if the vapor pressure of a liquid doubles when the temperature is raised from 87 degrees C to 98 degrees How many joules of heat are necessary to raise ...
Calculate the energy needed to heat 25 g of water from 65 degrees Celsius to steam at 145 degrees Celsius. How much energy is needed to heat 19.0 grams of water from 29.0 degrees Celsius to 100.0 degrees Celsius? How much energy is required to heat 81.0 ...
However, you will need to divide the tube into smaller sections with uniform diameter and calculate the volume for each section separately before adding them together for the total volume. Is the molten polymer tube model applicable to all types of polymer tubes?
