When working with the properties of Saturated Steam.
The pressure table supplied states:
Pressure kPa = 1100 (P)
Temp in Celsius = 184.09 (T)
Specific Volume = Sat. Liquid = 1.1330 (Vf)
Specific Volume = Sat.Vapor = 177.53 (Vg)
Enthalpy = Saturated Liquid = 781.34 (Hf)
Enthalpy = Evap = 2000.4 (Hfg)
Enthalpy = Saturated Vapor = 2781.7 (Hg)
Now using the information supplied:
Calculate the volume of 12kg of water at a pressure of 1100kPa, the answer is 0.014m^3.
I need help finding which formula is used to find the answer. Thank you.
To find the volume of 12 kg of water at a pressure of 1100 kPa, we need to use the properties of saturated steam.
The specific volume (V) represents the volume per unit mass of the substance. In this case, we have the specific volume for saturated liquid (Vf) and saturated vapor (Vg).
The formula to calculate the volume is as follows:
Volume = Mass / (Specific Volume)
In this case, we are given the mass (12 kg) and the pressure (1100 kPa). However, we do not have the specific volume for water at a pressure of 1100 kPa. To find the specific volume at this pressure, we need to refer to the steam tables or use steam property calculators.
The specific volume for saturated liquid (Vf) and saturated vapor (Vg) provided in the pressure table corresponds to a different pressure value. Therefore, we cannot directly use these values.
To find the specific volume at the given pressure, you will need to refer to a steam table or use a steam property calculator. These resources will provide you with specific volume values for saturated steam at various pressures. Once you have the specific volume value at 1100 kPa, you can proceed with the calculation using the formula mentioned above.
Once you have obtained the specific volume at 1100 kPa, you can plug in the values of mass (12 kg) and specific volume into the formula to calculate the volume. The result should be 0.014 m^3.
I hope this explanation helps you understand how to find the volume of water in this specific scenario.
