What is HF HFG and HG?

What is HF HFG and HG?

hf- is the specific enthalpy of the saturated fluid under the listed property values. hg- is the specific enthalpy of the saturated gas/vapor under the same listed property values. hfg- is the difference of the specific enthalpy values of the substances at the listed conditions.

What is VF and VG in steam table?

vf = Specific volume of saturated water (liquid). vg = Specific volume of saturated steam (gas).

How do you find the specific volume of saturated water?

From the appropriate saturation table, at the given value of pressure or temperature we can find the values of vf and vg then use equation [5], v = vf + x(vg – vf), to find the specific volume.

What is saturated water?

Saturated water is one in which the water has attained maximum level of saturation (there are certain conditions like super saturated also). For example, in case of NaCl dissolved in water, the saturation level is 36g per 100ml of water at room temperature (28 degree celsius).

What is the quality of a saturated liquid?

0%
In thermodynamics, vapor quality is the mass fraction in a saturated mixture that is vapor; in other words, saturated vapor has a “quality” of 100%, and saturated liquid has a “quality” of 0%.

What is HF value?

HF(g) -271.1 kJ/mol. NO(g) 90.25 kJ/mol.

What is a saturated liquid?

Saturated liquid: A liquid that is about to vaporize. At 1 atm and 20°C, water exists in the liquid phase (compressed liquid). At 1 atm pressure and 100°C, water exists as a liquid that is ready to vaporize (saturated liquid). Page 5.

What is saturated volume?

On the contrary Vs (volume saturated) is the volume a gas mixture would have if humidity was added to it until saturation (or 100% relative humidity).

Is saturated water liquid?

Saturated liquid: A liquid that is about to vaporize. At 1 atm and 20°C, water exists in the liquid phase (compressed liquid). At 1 atm pressure and 100°C, water exists as a liquid that is ready to vaporize (saturated liquid).

What is saturated water pressure?

: the pressure of a vapor which is in equilibrium with its liquid (as steam with water) specifically : the maximum pressure possible by water vapor at a given temperature.

What is difference between saturated liquid and compressed liquid?

Saturated liquid is a type of liquid in which no kind of solute can be added for that temperature. Compressed liquid, on the other hand, is defined as the extra punch or extra pressure that is being given or applied in relation to a type of pressure called atmospheric pressure.

What are the different types of water measurement units?

Water Measurement Units and Conversion Factors 1 Water Measurement Units. There are two conditions under which water is measured—water at rest and water in motion. 2 Volume Units. 3 Flow Units. 4 Conversion Factors. 5 Using Conversion Table. 6 Conversion between English and Metric Units.

What are the two conditions under which water is measured?

There are two conditions under which water is measured—water at rest and water in motion. Water at rest is measured in units of volume. Water in motion is measured in units of flow— unit of volume for a convenient time unit. It is important that the difference between a unit of volume and a unit of flow be kept in mind.

How much water was used during the month of June?

Step 1. The total depth of water use during June was 0.45 × 30 (days) = 13.5 inches. Step 2. The total volume of water use was 13.5 × 60 (acres) = 810 acre-in. Step 3. This volume is equal to 2,940,300 cubic-ft (row 2 in conversion table) or 22,052,250 gallons (row 1 in conversion table).

What units do farmers use to measure water?

Agricultural producers in many parts of the world use Metric (also called SI) units in their routine water measurements. The most commonly-used volume units in Metric system include liter, cubic meter, and hectare-millimeter, while common flow units are liter per minute (lpm) and cubic meter per second (cms).
