The convective heat transfer coefficient of air at the outer side can vary depending on factors such as the flow regime, surface roughness, temperature gradient, and air velocity. Typically, for natural convection, it can range from 5 to 25 W/m^2K, while for forced convection it can range from 25 to 100 W/m^2K.

What is the value of convective heat transfer coefficient of water having steel imerged?
The convective heat transfer coefficient between water and steel surfaces can vary depending on factors like temperature, flow rate, and surface roughness. However, typical values for this coefficient range from 500 to 10,000 W/m^2*K.
What is the convective heat transfer coefficient for air at 190 degrees?
The convective heat transfer coefficient for air at 190 degrees Celsius depends on the specific conditions of the system, such as velocity, geometry, and surface roughness. In general, it ranges from about 10 to 100 W/m^2*K for natural convection and can be higher for forced convection. Conducting a detailed analysis or using correlations specific to your system would provide a more accurate value.
What is Overall Heat transfer coefficient?
The overall heat transfer coefficient represents the rate at which heat is transferred between two mediums per unit area and per unit temperature difference. It combines the individual resistances to heat transfer in conduction, convection, and radiation into a single value. A higher overall heat transfer coefficient indicates a more efficient heat transfer process.
What is the average value of coefficient of velocity in a submerged orifice?
The average value of the coefficient of velocity for a submerged orifice is typically around 0.97 to 0.99. This value represents the efficiency of the orifice in converting the potential energy of the fluid into kinetic energy.

The overall heat transfer coefficient represents the rate at which heat is transferred between two mediums per unit area and per unit temperature difference. It combines the individual resistances to heat transfer in conduction, convection, and radiation into a single value. A higher overall heat transfer coefficient indicates a more efficient heat transfer process.
What is the value of an overall heat transfer coefficient in an engine oil cooler?
I have a book (Introduction to heat transfer - Bergmann), there is an example of an oil cooler cooled by air (crossflow heat exchanger with both fluids unmixed). There is written: "... with an overall heat transfer coefficient of 53 W/(m²*K)."
