The water temperatures at the inlet and outlet of the radiators in each layer are different; B. The heat transfer coefficients of the radiators in each layer are different; C. The pressures due to circulation in each layer are different; D. The water supply temperature or flow rate does not meet the design requirements
C Because the pressures differ due to the cyclic action across various layers
