**Text:**

The upper surface of a 50-cm-thick solid brass plate (k=109 W/m·K) is being cooled by water with a temperature of 10°C. The upper and lower surfaces of the solid plate are maintained at constant temperatures of 60°C and 190°C, respectively. Determine the water convection heat transfer coefficient and the water temperature gradient at the upper plate surface.

---

**Diagram Description:**

The diagram depicts a horizontal, rectangular solid brass plate. The plate is 50 cm thick. Water flows over the upper surface of the plate, as indicated by several parallel arrows pointing to the right, labeled "Water." Two points on the plate surfaces are labeled with temperature variables:

- \( T_{x,1} \) indicating the temperature of the upper surface at 60°C.
- \( T_{x,2} \) indicating the temperature of the lower surface at 190°C.

The diagram illustrates the cooling process where water influences the temperature and heat transfer at the upper surface of the brass plate.
