Answer:
The speed of nitrogen molecule is 1.87 m/s.
Explanation:
Given that,
Pressure = 2 atm
Density = 1.7 grams/liter
Atomic weight = 28 grams
We need to calculate the temperature
Using formula of idea gas
Put the value into the formula
We need to calculate the speed of nitrogen molecule
Using formula of RMS speed
Hence, The speed of nitrogen molecule is 1.87 m/s.
Answer:3764.282 KPa
Explanation:
Given gusher shoots oil at h=25 m
i.e. the velocity of jet is
v=\sqrt{2gh}[/tex]
v=22.147 m/s
Now the pressure loss in pipe is given by hagen poiseuille equation
For 25 m head in terms of Pressure
Total Pressure==3543.557+220.725=3764.282 KPa
Answer:
2 rad/s
Explanation:
For a rotating object, the linear velocity is given by
where is the angular velocity and
is the radius.
The edge has a linear velocity of 10 m/s and the radius at the edge is 5 m.
