If the operator initially drives the pedals at 20 rev/min, and then begins an angular acceleration of 30 rev/min², determine the angular velocity of the flywheel F when t = 35. Note that the pedal arm is fixed connected to the chain wheel A, which in turn drives the sheave B using the fixed connected clutch gear D. The belt wraps around the sheave then drives the pulley E and fixed connected flywheel.

1- Water vapor at a flow rate of 20000 kg / hour enters a steam boiler with a specific volume of 150 kPa 0.001053 m3 / kg. With the energy it takes from the fuel in the combustion chamber of the boiler, it rises at 150˚C at 1200 kPa. If the boiler has poor insulation and loses 100 kW of heat to the environment, calculate the time required to increase 1 ton of water to 150 ° C in the boiler.
