3 components of an expressway are :

Acceleration Lane

Merging Area

Slow Lane

Safety design features of an expressway:

Safety elements on the freeways include lane separators and shoulders. Broad, clearly indicated lanes: Highway lanes are broad and feature distinct markings. The inside edge of paved shoulders often has elevated or grooved patterns called "rumble strips" that are typically found alongside major highways.

What are expressways designed for?

Instead of the current practice of every business or establishment connecting the main roadway, access restricted roads have a limited number of designated entry and exit points. Coming onto the main highway is done via segregated service roads.

Calculate the mass of water vapour present in a room of volume 400 m3 that contains air at 27 °C on a day when the relative humi

Alex73 [517]

Answer:

Mass of water = 6251. 706g or 6.25Kg

Explanation:

Relative humidity = (actual vapor pressure/saturation vapor pressure) * 100%

Actual vapor pressure, Pw = relative humidity * saturation vapor pressure

Pw = 60% * (35.6 *0.001)atm = 0.0216atm

Note: 1mbar = 0.001atm

Using the ideal gas equation: PV=nRT; where P = Pw= 0.02136atm, V= (400

* 1000)dm^3, R= 0.082 atmdm^3/kmol, T= (27+273)K, n = number of moles

Note: 1m^3 = 1000dm^3,R is the molar gas constant.

Making n subject of the formula, n = PV/RT

n= (0.02136 * 400000)/(0.082 * 300) = 347.317 moles

Mass (g) = number of moles (n) * molar mass

molar mass of water=18g

Mass of water = 347.317 * 18 = 6251. 706g or 6.25Kg

if the atmospheric pressure is 1 atm. then what would the pressure (in torr) be of nitrogen, oxygen and argon be in the air?

Anna007 [38]

The pressure of just nitrogen, oxygen, and argon in the air is 0.78 atm, if the total atmospheric pressure is 1.00 atm.

What distinguishes atmospheric pressure from air pressure?

As opposed to atmospheric pressure, which refers to the force of the earth's atmosphere, air pressure is the force of the air around us. Mercury barometers are used to measure atmospheric pressure, while tore gauges are used to measure air pressure.

Why is atmospheric pressure created?

What applies pressure on the atmosphere is the mass of the air molecules above. It weighs down on whatever is underneath because of the massive quantity of air molecules that collectively make up the layers of our atmosphere. Air molecules of all sizes carry some weight.
