Explanation A closed system is a system where no exchange of material takes place with surroundings. In energy balance equation to a reacting closed system, the energy change is defined as the energy change of kinetic energy, potential energy and internal energy. Express the form of energy balance for the closed system in the absence of kinetic and potential energy effects. U P − U R = Q − W Here, internal energy of the reactants is U R , internal energy of products is U P , heat transfer or absorb is Q and work done is W . Express the energy balance if the reactants and products form ideal gas mixtures. ∑ P n u ¯ − ∑ R n u ¯ = Q − W Here, coefficients of the reaction equation giving the moles of each reactant and product is n and specific internal energy is u ¯

Ashaft fitted with a flywheel rotates at 300 rpm. and drives a machine. The torque required to drive the machine varies in a cyclic manner over a period of 2 revolutions. The torque drops from 20,000 Nm to 10,000 Nm uniformly during 90 degrees and remains constant for the following 180 degrees. It then rises uniformly to 35,000 Nm during the next 225 degrees and after that it drops to 20,000 in a uniform manner for 225 degrees, the cycle being repeated thereafter. Determine the power required to drive the machine and percentage fluctuation in speed, if the driving torque applied to the shaft is constant and the mass of the flywheel is 12 tonnes with radius of gyration of 500 mm. What is the maximum angular acceleration of the flywheel. 35,000 TNM 20,000 10,000 0 90 270 495 Crank angle 8 degrees 720
