Gasoline flows in a long, underground pipeline at a constant temperature of 15o C (rho = 680 kg/m3 ; ν = 4.6 × 10-7 m2 /s). Two
pumping stations are located at the same elevation 13 km apart. The pressure drop between the stations is 1.4 MPa. The diameter of the pipe is 0.6 m and has a roughness of ε = 0.12 mm. Determine the volume flow rate.

Answer:
option E
Explanation:
given,
angular speed of bicycle tire ()= 3.80 rad/s
time period = 2.35 s
tire stops and spun in opposite direction with angular velocity = 3.80 rad/s
average angular acceleration
initial angular speed = ω₀ = - 3.80 rad/s
final angular speed = ω₁ = 3.80 rad/s
change in angular velocity
average angular acceleration
approximately equal to 3.4 rad/s²
the correct answer is option E
