30 PSIG is about equal to 45 PSIA. Saturation temperature from the steam tables at 45 PSIA is about 274°F. So the steam would be 274°F, or hotter if superheated.
1. Low vacuum at high loads 2. High HRH temp 3.High steam flow 4. high gland steam temperature
When Turbine shaft temp is below 100 deg.centigrade,Then rolling of turbine carried out it is called cold rolling.
Most steels have Young Modulus, E, of 30 million psi and Poisson ratio, u, of about 0.30 Shear Modulus = E/2/(1+u) = 30/2.6 = 11.5 million psi
IT is not accurately 535 c.... The water should be in the super heated condition... So we go to like a higher temperature region and also higher pressure region to change the steam as super heated steam and then the steam is allowed to expand in the steam turbine... now the power gained is much higher than the water flowes at saturated condition like (200 c - 300 c )... so only we are moving to higher temperature and higher pressure region
About 29-30 million psi, depending on type of steel, but close enough for most steels.
The temperature of 70 psi steam is approximately 318°F.
It takes more energy to keep steam at 30 psi because higher pressure requires more energy to maintain the temperature and pressure of the steam. More energy is needed to overcome the increased resistance at higher pressures.
The temperature of 110 psi steam is approximately 338 degrees Fahrenheit.
The steam temperature at 10 PSI is approximately 239 degrees Fahrenheit.
RUN!
The temperature of 50 psi steam is approximately 298°F (148°C).
Water temp 180-200 deg. Pressure 18-22 psi.
30kPa= 4.35 psi
10 psi minimum, 30 psi would be better.10 psi minimum, 30 psi would be better.
At 20 PSI (pounds per square inch), the temperature of steam is typically around 250°F (121°C).
The energy content of steam at a given pressure, such as 150 psi, depends on the specific volume and temperature of the steam. To determine the number of joules, you would need more specific information about the steam properties.
1psi = 0.068 atm. So to convert 30 psi using dimensional analysis... 30 psi x 0.068 atm/1 psi = 2.04 atm
