How does the design of the primary circuit affect the operation of the secondary circuit?

The design of the primary circuit, including the pump selection and piping layout, has a significant impact on the operation of the secondary circuit. For example, a primary circuit with a high-pressure drop will result in a greater flow rate in the secondary circuit, while a primary circuit with a low-pressure drop will result in a smaller flow rate. Therefore, careful design of the primary circuit is necessary to ensure proper operation of the secondary circuit.
