T1 = 46
T2 = 16
The total heat transfer can be broken into two parts: heat given off and eat absorbed (if we assume the system is closed). The heat absorbed goes into the ice, to turn it into ice water the resulting ice water, to raise it to T2 The heat given off comes from . the reservoir the water in the reservoir the thermometer all of which start out at Ti Assuming the system is closed, all...

, a variable resistor () and a resistor of fixed resis The figure below shows an electric circuit containing a source of em tance R. The resistor R is immersed in a sealed beaker containing a mass m of water, currently at temperature T When the switch S is closed, current through the circuit causes the resistor in the water to dissipate heat, which is absorbed by the water A stirrer at the bottom of the beaker simply ensures that...

True or False/Short Answer Questions The ramp response of a 1st order system can be oscillating. Using the state space representation, the number of rows in the matrix B is equal to the number of outputs. Closed-Loop Control systems are insensitive to external disturbances. Two physically different systems must be modeled by two different transfer functions. For an LTI system, the time derivative of the unit impulse response is the unit ramp response. If a system has two real and...
