Unformatted text preview: difference between the room and the beer. The heat flowing into the can will cause the beer to get warmer. The rate at which the beer will get warmer depends upon the heat transfer rate, the mass of beer present, and the specific heat of the beer (the amount of heat required to make a unit mass of beer one degree C warmer). Using the symbols given below, derive an equation relating the temperature of the beer ( T B ) to the temperature of the room ( T R ). Assume that the thickness of the can be neglected. U = overall heat transfer coefficient (in kJ per second per m 2 of can area per degree C) h = height of can (in m) d = diameter of can (in m) = density of beer (in kg/m 3 ) c p = specific heat of beer (in kJ per kg per degree C) Is this system analogous to any of the examples in part 1 of the notes? 3/. Derive the defining equation for the system shown below: 4/. For the op-amp circuit shown below, derive an expression for V OUT in terms of V IN ....
