Use mesh-current method to find the power developed in the voltage source in the circuit in fig. p4.28.
how do i simplify the circuit to solve it? (preferably using source transformation)

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Determine (a) the maximum thermal efficiency of reversible power cycles operating between a hot reservoir at 1000°c and a cold reservoir at 200°c and (b) the maximum cops for reversible refrigeration and heat pump cycies, respectively, between 28°c and 14°c.
