Consider a cube of density, specific heat, and thermal conductivity of 2700 kg/m3, 0.896 kJ/kg-K, and 204 W/m-K, respectively. The cube is 5 cm in length, and is initially at a temperature of 20 oC. For t>0, two of the boundary surfaces are insulated, two are subjected to uniform heating at a rate of 10,000 W/m2, and two dissipate heat by convection to an ambient temperature of 20 oC, with a heat transfer coefficient of 50 W/m2-K. Assuming lumped capacitance...

A 1-shell-2-tube pass heat exchanger is made of a steel alloy (thermal conductivity 45.4 W/(m K). It is used to cool distilled water from 34oC to 29oC using water which flows inside tubes with an outer diameter of 19 mm and an inner diameter of 16 mm. The number of tubes in the shell is 160 (80 per pass). The mass flow rate of distilled water in the shell is 76180 kg/h. The cold water enters the heat exchanger at...

The extent to which the tip condition affects the thermal performance of a fin depends on the fin geometry and thermal conductivity, as well as the convection coefficient. Consider an alloyed aluminum (k = 180 W/m*K) rectangular fin of length L = 10 mm, thickness t = 1 mm, and width w >> t. The base temperature of the fin is Tb = 100°C, and the fin is exposed to a fluid of temperature T∞ = 25°C. Assuming a uniform...

Problem 2. (20 pts) You would like to know the heat transfer coefficient from a cooling fin operating under forced convection, but with a length of 1 cm the real fin is just too small to make any measurements. You make a 10x scale model and test it at the real operating temperatures and 1/10th the ambient airflow velocity. If your scale model has an h of 5.14 W/m2/K, what is the value of h for the real fin? In...

It's a heat transfer question. A stainless steel fin with a constant base temperature (900K) and with an insulated end. Apply convection at all cylindrical surfaces except the base and the tip. The convection coefficient, h = 50 W/(m2·K), and fluid temperature of T∞ = 300K. Plot the temperature distribution along the center axis line (T vs x). Include a contour plot across the cross section of the fin. Assume zero contact resistance between the sections. K=19.8W/m-k Cp=557J/Kg-K Rho= 7900Kg/m^3...

Liquid water flows in a long pipe of internal diameter of D = 0.01 m at a mean velocity of V = 0.065 m/s. The pipe is maintained at a constant and uniform surface temperature. Assume the flow is both hydrodynamically and thermally fully developed. For simplicity, evaluate the properties of water at 300 K. Calculate the convective heat transfer coefficient of the flow inside the pipe in W/m2K?

Question 2. Answer all parts of this question a) A shell and tube heat exchanger is to heat 10,000 kg h–1 of water from 16 to 84°C using hot oil entering at 160°C and leaving at 92°C. The oil will flow through the shell of the heat exchanger. The water will flow through 11 brass tubes of 22.9 mm inside diameter and 25.4 mm outside diameter, with thermal conductivity 137 W m–1 K–1, with each tube making two passes through...
