What is interpolation method in thermodynamics?

Description. Linear interpolation is a way to fill in the “holes” in tables. As an example, if you want to find the saturated pressure of water at a temperature of 40 C you can look in Table B. You could of course just ignore the difference between 38 C and 40 C, and still take the saturated pressure to be 7.384 kPa.

What is meant by saturated ammonia?

[′sach·ə‚rād·əd ə′mō·nyə] (chemistry) Liquid ammonia in a state in which adding heat at constant pressure causes the liquid to vaporize at constant temperature, and in which removing heat at constant pressure causes the temperature of the liquid to drop immediately.

What are properties of ammonia?

Some chemical/physical properties of ammonia are: At room temperature, ammonia is a colorless, highly irritating gas with a pungent, suffocating odor. In pure form, it is known as anhydrous ammonia and is hygroscopic (readily absorbs moisture). Ammonia has alkaline properties and is corrosive.

How do you calculate 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.

How do you interpolate two values in a table?

Know the formula for the linear interpolation process. The formula is y = y1 + ((x – x1) / (x2 – x1)) * (y2 – y1), where x is the known value, y is the unknown value, x1 and y1 are the coordinates that are below the known x value, and x2 and y2 are the coordinates that are above the x value.

How much heat does ammonia have at triple point?

Ammonia Latent heat of fusion (1,013 bar, at triple point) : 331.37 kJ/kg. Ammonia Liquid Density (1.013 bar at boiling point) : 682 kg/m3 (250 K : 669 kg/m3) (300 K : 600 kg/m3) (400 K : 346 kg/m3) Ammonia Liquid Specific Heat (cp) (250 K : 4.52 kJ/kg.K) (300 K : 4.75 kJ/kg.K) (400 K : 6.91 kJ/kg.K)

What is the specific entropy of ammonia NH 3?

How is the thermal conductivity of ammonia determined?

For full table with Specific Entropy and Superheated Properties – rotate the screen! Ammonia Liquid Thermal Conductivity (250 K : 592 106 kW/m.K) (300 K : 477 106 kW/m.K) (400 K : 207 106 kW/m.K) Ammonia Critical point – Critical temperature : 132.4oC – Critical pressure : 112.8 bar

What is the pressure and viscosity of ammonia?

Ammonia – Dynamic and Kinematic Viscosity – Online calculator, figures and tables showing dynamic (absolute) and kinematic viscosity of gasous and liquid ammonia at temperatures ranging from -73 to 425°C (-100 to 800°F) at pressure ranging from 1 to 1000 bara (14.5 – 14500 psia) – SI and Imperial Units.
