The battery powers the motor that drives a paddle wheel to stir the gas at unifo

Question

The battery powers the motor that drives a paddle wheel to stir the gas at uniform pressure and temperature. The motor is diathermal and the tank containing the gas is also diathermal. The battery is adiabatic. Choose the gas as the system. Show the system from a thermodynamic point of view and the energy (rate) interactions between the system and the surrounding using proper arrows, and label them clearly, e.g., and . Furthermore, overload the latter with appropriate subscripts to describe electric work, paddle wheel work, etc. The paddle wheel power is 0.88 kW. Determine the rate of heat transfer between the system and the surrounding if there is no change in the rate of internal energy of the gas. Determine the angular speed in rpm if the torque necessary to spin the paddle wheel is 16.807 N.m. Choose the motor as the system. Show the system from a thermodynamic point of view and the energy (rate) interactions between the system and the surrounding using proper arrows, and label them clearly, e.g., and . Overload the latter with appropriate subscripts. The motor operates at steady state. What is the rate of change of the motor internal energy? The rate of heat transfer from the motor to the surroundings is 20% of the input power to the motor. Find the input power to the motor in kW. Choose the battery as the system. Show the system from a thermodynamic point of view and the energy (rate) interactions between the system and the surrounding using proper arrows, and label them dearly, e.g., and . Overload the latter with appropriate subscripts. The battery operates at 110 Volts. What is the current drawn by the motor in amp? What is the rate of change of the battery internal energy in kW?
