4. S.

What is atmospheric at sea level?

Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.

How do you find the density of air at sea level?

Calculation of Air Density

1. R is the Gas constant = 287.05 J/kg-K.
2. T is the temperature in K. Air is assumed to be at 20°C so, T = (20 + 273.15)
3. P is standard pressure:
4. Z = Elevation above sea level (m)

What is the density at sea level?

about 1.225 kg / m3
Typical air density at sea level is about 1.225 kg / m3 .

What is the coefficient of dynamic viscosity of air at sea level?

Dynamic viscosity, = 1.789×10−5 Pa·s ⇔ 3.737×10−7 slug/(s·ft)

What is the air pressure at sea level in millibars?

1013.25 millibars
At sea level, the weight of the air above this unit area would (on average) weigh 14.7 pounds! That means pressure applied by this air on the unit area would be 14.7 pounds per square inch. Meteorologists use a metric unit for pressure called a millibar and the average pressure at sea level is 1013.25 millibars.

Why is atmospheric pressure highest at sea level?

Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing altitude.

What is the basic unit of viscosity?

The unit of viscosity, accordingly, is newton -second per square metre, which is usually expressed as pascal -second in SI units. The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature.

What is CGS unit of viscosity?

The most commonly used unit for dynamic viscosity is the CGS unit centipoise (cP), which is equivalent to 0.01 Poise (P).

What is the viscosity of air at STP?

1) The dynamic viscosity of air at STP is 17.89 Mu N s/m^2 (that is micro Ns/m^2) Calculate the corresponding value in Poise (P), and lbf s/ft^2.

What are the dimensions of viscosity?

The dimensions of viscosity can be determined based on how it is defined. It is defined as the property of a fluid that describe a stress (force/area) per velocity shear rate in the fluid (d velocity/d distance). So the dimensions are (F/A)/(V/L). That can be rearranged to F/(At) = F/(L^2 t). That could be changed to (m L/t^2)/(L^2 t) = m/(Lt).
