Heat transfer questions pdf

8. Sensible heat is the heat required to. (a) change vapour into liquid. (b) change liquid into vapour. (c) increase the temperature of a liquid of vapour. (d) convert water into steam and superheat it. (e) convert saturated steam into dry steam. Ans: c. Heat Transfer Cut out the boxes and sort them on the graphic organizer on the next page. Glue the final product in your notebook. Microwave Hot air popper plate/burner Transfer of heat through contact with EM wastes Transfer of heat through a fluid that moves in currents — hot air rises cools then falls Transfer of heat through direct Heat transfer from the moving fluid to solid surface is given by the equation. Q = h A = [Tw - T]; This equation is referred to as Newtons law of cooling. Where h = Local heat transfer coefficient in W/m2K. A = Surface area in m2. Tw = Surface [or] Wall temperature in K. T = Temperature of fluid in K. 17. What is forced convection? Heat transfer MCQ Question 1 Download Solution PDF What kind of transfer of heat involve while you boil water in the pot?

Heat transfer co-efficient for the cooling water, whether on shell side or tube side is the same. The best arrangement is (A) Vertical heat exchanger with steam on tube side increase the shell side heat transfer co-efficient. decrease the shell side heat transfer co-efficient. Answer : 3. Question 20 : Air is to be heated by condensing steam. Two heat exchangers are available (i) a shell and tube heat exchanger and (ii) a finned tube heat exchanger. Tube side heat transfer area are equal in both the cases. Heat Transfer Test _____ Instructions: Encircle the letter of your choice for the following questions. 1. Abigail noticed that metal gets very cold during winter, colder than other materials such as wood and D. Heat is transferred from warm objects to cool objects that are in contact with each other. 1. Define Heat Transfer? Heat transfer can be defined as the transmission of energy from one region to another due to temperature difference. 2. What Are The Modes Of Heat Transfer?
