Design a heat exchanger for a process where hot air (80°C) needs to be cooled down to 30°C using water (10°C) as the cooling medium. The flow rate of hot air is 2 kg/s and the desired outlet temperature of the cooled air is 35°C. The maximum allowable pressure drop for air side is 50 kPa and for water side is 100 kPa. Design the heat exchanger using the LMTD (logarithmic mean temperature difference) method and calculate the required area of heat transfer.

The axon terminates on muscle fibers at the neuromuscular junction. acetylcholine is released at this specialized synapse, which causes the muscle action potential to begin, following a large potential known as an end plate potential. when the lower motor neuron excites the muscle fiber, it contracts. all of this occurs in a fraction of a second, but this story is the basis of how this functions?
