The angular acceleration of a flywheel decreases uniformly from 9 rad per sec² to 3 rad per sec² in 6 sec at which time its angular velocity is 42 rad per sec. Compute the initial angular velocity and the number of revolutions made during the 6-sec interval. Note: Draw the diagram/s before formulating any equation.

Fluid mechanics- Bernoulli's Equation along a streamline: The flow-metering device shown consists of a stagnation probe at station 2 and a static pressure tap at station 1. The velocity at station 2 is twice that at station 1. Air with a density of 1.2kg/m3 flow through the duct. A water manometer is connected between the stagnation probe and the pressure tap, and a deflection of 10cm is measured. What is the velocity at station 2?
