ABSTRACT
If this unit is cycled with a displacement x = 1.0 sin lOt inches (tin seconds), what is the time-average rate of heat generation in watts? Heat transfer calculations show that the damper can transfer heat to its surroundings at the rate of 5.0 watts for each degree of temperature rise above ambient. What will be the steady-state average operating temperature of this damper if ambient temperature is 70°F? Using this
temperature, select a suitable fluid from Appendix A. If this damper is inactive and then starts cycling as above, what will be the B value when it first starts cycling?
