A Ferris Wheel, starting from rest, undergoes a constant angular acceleration of 0.033 rad/s2 to get to its final operating angu
1 answer:
Answer:
The time taken for the Ferris Wheel to get the final angular velocity is 7.27 s.
Explanation:
Given;
initial angular velocity of the Ferris Wheel, = 0
angular acceleration, α = 0.033 rad/s²
final angular velocity, = 0.24 rad/s
The time taken for the Ferris Wheel to get the final angular velocity is calculated as;
Therefore, the time taken for the Ferris Wheel to get the final angular velocity is 7.27 s.

Answer:
Given that
Dry-bulb temperature(T) =24°C
Wet-bulb temperature(Tw) = 17°C
Pressure ,P = 1 atm
As we know that psychrometric chart are drawn at constant pressure.
From the diagram
ω= specific humidity
Lets take these two lines Dry-bulb temperature(T) line and Wet-bulb temperature(Tw) cut at point P
From chart at point P
a)
Specific humidity,ω = 0.00922 kg/kg
b)
The enthalpy ( h)
h=47.59 KJ/kg
c)
The relative humidity, RH
RH= 49.58 %
d)
Specific volume ,
v= 0.853 m³/kg
