Air conditioning refrigerant contains Freon R22 and R410a, which have been linked to environmental damages, including ozone depletion, global warming, and energy-inefficiency. For environmentally-savvy entities and individuals, there is the modern move to a more environment-friendly refrigerant, known as R-32. Technician A's advice to vent the refrigerant outside the shop is in bad taste. He does not seem to be aware of the environmental footprint of such an action. Venting gas outside, in addition to the environmental damages, is also a waste of resources, and therefore, costly. This is why Technician B's advice should be preferred.

An airliner is flying at 34,000 ft cruise altitude on a standard day. Calculate the pressure difference between the cabin and th

nadya68 [22]

Answer:

$\Delta P=61,952.8\ lb/ft^2$

Explanation:

Given

Airline flying at 34,000 ft.

Cabin pressurized to an altitude 8,000 ft.

We know that at standard condition ,density of air

$\rho =0.074\ lb/ft^3$

We know that pressure difference

ΔP=ρ g ΔZ

Here ΔZ=34,000-8,000 ft

ΔZ=26,000 ft

$g= 32.2\ ft/s^2$

ΔP=0.074 x 32.2 x 26,000

$\Delta P=61,952.8\ lb/ft^2$

So pressure difference will be $\Delta P=61,952.8\ lb/ft^2$ .
