Heat Transfer Qts
Engine oil at 60 oC flows over flat plate whose temperature is at 20 oC with a velocity of 2 m s-1. The length of the plate is 5m. What is the film temperature and the rate of heat transfer per unit width of the entire plate?
Additional information (at the film temperature):
Thermal conductivity of oil: Prandtl number:
Dynamic viscosity:
k1 = 0.144 W m-1 K-1
Pr = 2870
u = 0.21 kg m-1 s-1

Help!
Can't get a Reynolds number without density..
Is film temperature 40 degrees Celsius?

Qts solved..
Was right..lecturer wrong AGAIN..was then provided with engine oil density
 

1. What is chemical engineering heat transfer qts?

Chemical engineering heat transfer qts refers to the study and application of the principles of heat transfer in the field of chemical engineering. It involves understanding how heat is transferred between different substances and how to control and optimize this process for various industrial applications.

2. What are the different types of heat transfer in chemical engineering?

The three main types of heat transfer in chemical engineering are conduction, convection, and radiation. Conduction is the transfer of heat through a solid material, convection is the transfer of heat through a fluid, and radiation is the transfer of heat through electromagnetic waves.

3. How is heat transfer used in chemical engineering processes?

Heat transfer is used in chemical engineering processes to control and optimize the temperature of chemical reactions, to maintain the stability of products, and to increase the efficiency of energy usage. It is also used in the design of heat exchangers and other equipment used in chemical processing.

4. What factors affect heat transfer in chemical engineering?

The factors that affect heat transfer in chemical engineering include the temperature difference between two substances, the thermal conductivity of the materials involved, the surface area and geometry of the system, the type of fluid flow, and any barriers or insulators present in the system.

5. How is heat transfer calculated in chemical engineering?

Heat transfer in chemical engineering is calculated using various equations and principles, such as Fourier's law of heat conduction, Newton's law of cooling, and the Stefan-Boltzmann law of thermal radiation. The specific calculations used depend on the type of heat transfer and the system being analyzed.
