Steam at a pressure of 900kPa has an entropy of 4.9678 kJ/kg0K. Find out if the steam is saturated, wet or superheated steam. What are the specific volume, internal energy and enthalpy.
To determine whether the steam is saturated, wet, or superheated, we need to compare its pressure and entropy values to the saturated steam tables.
1. Start by looking up the saturation pressure corresponding to the given entropy value. The entropy value of steam can help us determine if it's in a saturated or superheated state.
2. Once we find the saturation pressure, we can compare it to the given pressure of 900 kPa. If the given pressure is less than the saturation pressure, the steam is in a saturated state. If the given pressure is greater than the saturation pressure, the steam is superheated.
3. Calculating the specific volume, internal energy, and enthalpy requires additional information, such as temperature or quality. Since the given information doesn't include any temperature or quality values, we can go back to the saturation tables to obtain these properties based on the determined state of the steam.
Now, let's go step by step through the process to find if the steam is saturated, wet, or superheated, and calculate the specific volume, internal energy, and enthalpy.
Step 1: Determine State of Steam
Using the saturation tables, we find that the saturation pressure corresponding to the given entropy value of 4.9678 kJ/kg·K is 2780 kPa.
Step 2: Compare Pressure Values
Given pressure: 900 kPa
Saturation pressure: 2780 kPa
Since 900 kPa is less than 2780 kPa, the steam is saturated.
Step 3: Calculate Specific Volume, Internal Energy, and Enthalpy
To calculate the specific volume, internal energy, and enthalpy, we need to know the temperature or quality of the saturated steam. Unfortunately, this information is not provided in the question.
To find these properties, refer to the steam tables using the saturation temperature corresponding to the given saturation pressure of 2780 kPa. From there, you can determine the specific volume, internal energy, and enthalpy based on either temperature or quality.
Please note that without temperature or quality information, we cannot provide specific numerical answers for the specific volume, internal energy, and enthalpy.
