In the United States, fire codes are developed primarily by two model code organizations, the International Code Council (ICC) and the National Fire Protection Association (NFPA).
Answer:
use the dimensions shown in the figure
Answer:
G =67.74
Explanation:
Given that
length l=2.4 m
Outside diameter= 16 cm
Inside diameter= 15 cm
Speed N =900 RPM
We know that
Where r is the radius V is the velocity.
So mean radius
r = 7.5 cm
We know that
V=ω x r
V= 94.24 x 0.075 m/s
V= 7.06 m/s
G =67.74
Answer:
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
Answer:
v = 1.076 m /s
Explanation:
Initial volume of balloon = 4/3 x 3.14 x (9.905/2)³
=508.56 m³
Final volume of balloon = 4/3 x 3.14 x (16.502/2)³
= 2351.73 m³
Increase in volume = 1843.17 m³
Cross sectional area of inlet A = 3.14 x( 1.458/2)²
A = 1.6687 m²
Volume rate of flow of air = cross sectional area x velocity of inflow
= 1 .6687 V [ V is velocity of inflow ]
Total time taken = Increase in volume / rate of flow of air
17.108 X 60 = 1843.17 / 1.6687 V
V =
v = 1.076 m /s
