### Understanding Fluid Flow in Crossflow Heat ExchangersCrossflow heat exchangers are vital in various industrial applications due to their efficiency in heat transfer. Understanding the fluid movement in these exchangers can enhance system design and performance. **Question:** Which of the following is true about the flow of fluids in crossflow heat exchangers?- **a.** Fluids move at an angle of 60 degrees to each other.- **b.** Fluids move perpendicular to each other.- **c.** Fluids move at an angle of 45 degrees to each other.- **d.** Fluids are moving in the same direction, in parallel.#### Explanation:In crossflow heat exchangers, option **b** is correct: fluids typically move perpendicular to each other. This configuration allows for efficient heat exchange between the two fluids, as it maximizes the surface area available for heat transfer, while minimizing the required physical space.Understanding the flow direction is crucial in optimizing the exchanger's performance and ensuring the desired thermal efficiency.

Which of the following is true about the flow of fluids in crossflow heat exchangers? O a. Fluids move at an angle of 60 degrees to each other O b. Fluids move perpendicular to each other. O c. Fluids move at an angle of 45 degrees to each other. O d. Fluids are moving in the same direction, in parallel.
