What does a psychrometric chart show?
Psychrometric Chart and Air Characteristics. A psychrometric chart presents physical and thermal properties of moist air in a graphical form. It can be very helpful in troubleshooting and finding solutions to greenhouse or livestock building environmental problems.
How do you find vapor pressure from psychrometric chart?
Locate the vapor pressure line to the right of the dew point line. Next to or along the same vertical line as the dew point measurements, there will be markings denoting the various vapor pressures in inches of mercury or millibars.
What is the difference between DBT and WBT called?
This reduced temperature measured by the thermometer is called as the wet bulb temperature. The wet bulb temperature of the air is always less than the dry bulb temperature of air. The difference between the DBT and WBT is called as wet bulb depression.
What is the specific volume of water?
The point where this maximum occurs is known as the critical point and the properties at this point are known as the critical properties. For water, for which this diagram is plotted, the critical pressure, temperature, and specific volume are, respectively, 22.06 MPa, 647.1 K, and 0.0560 m3/kg.
How do you find specific volume?
To calculate specific volume you need to know the volume (V) and the mass (m). Specific volume equals volume divided by mass. Typically, volume is measured in cubic meters (m3), and mass is measured in kilograms. Specific volume is then calculated as volume divided by mass.
Which out of following is not extensive property?
Molarity is the of the following is not an extensive property and molarity is the concentration of the solution and expressed as the number of moles of solute per liter of solution and Molarity = mole of solute/ liter of solution.
Which out of the following is not an intensive property?
Here, volume depends on the quantity of matter. Therefore, volume is not an intensive property.
Is stress an intensive or extensive property?
Stress is independent of mass. e) Extensive. If the mass doubles, the mass doubles.
Is internal energy an intensive property?
An intensive property, is a physical property of a system that does not depend on the system size or the amount of material in the system. According to the definitions, density, pressure and temperature are intensive porperties and volume, internal energy are extensive properties.
Is heat capacity an intensive or extensive property?
The heat capacity C of a substance is the amount of heat required to change its temperature by one degree, and has units of energy per degree. The heat capacity is therefore an extensive variable since a large quantity of matter will have a proportionally large heat capacity.
Is density an intensive or extensive property?
Density is an intensive property of matter that illustrates how much mass a substance has in a given amount of volume.
How internal energy is extensive property?
Internal energy is an extensive property—that is, its magnitude depends on the amount of substance in a given state. Its value usually is calculated with reference to some standard state rather than being expressed in absolute terms.
How energy is extensive property?
Energy, volume and enthalpy are all extensive properties. Their value depends on the mass of the system. For example, the enthalpy of a certain mass of a gas is doubled if the mass is doubled; the enthalpy of a system that consists of several parts is equal to the sum of the enthalpies of the parts.
