COURSE DESCRIPTION
In this course, we will learn how to solve problems related to Physical transport Phenomena (questions and exercises).
Let’s dive in;
A horizontal pipe with two sections of cross-sectional area 50cm2 and 25cm2 used for flow experiments in the Chemical and Petroleum Engineering laboratory. In one of the experiments the larger cross-sectional area has pressure and temperature of 4bar (absolute) and200C respectively. At the other section, the pressure was recorded to be 2bar (gauge). If the mass flowrate of the gas through the pipe is 0.6kg/s, find the velocities of the gas at these sections, assuming an isothermal change.

The large furnace in the material engineering lab that is enclosed with fire brick insulated wall has an internal temperature of 8150C. A small oxidized horizontal metal tube with an area of 0.5 ft2 with a surface temperature at 3150C is inserted in the furnace. The emissivity of the metal tube is 0.60 at 8150C and 0.46 at 3150C. What amount of hat is transferred to the tube by radiation?

A Cold storage room is constructed of an inner layer of 12.7 mm of pine, a middle layer of 101.6 mm of cork board, and an outer layer of 76.2 mm of concrete. The wall surface temperature is 255.4 K inside the cold room and 297.1 K at the outside surface of the concrete. Use conductivities for pine, cork board and concrete as 0.151, 0.0433 and 0.762 W/m.K respectively. Calculate the heat loss in W for 1m2 and the temperature at the interface between the wood and cork board.

A 3/4 in. steel pipe having an ID of 0.0687 ft. and an OD of 0.0875 ft. has saturated steam at 267 OF flowing inside. The pipe is insulated with 1.5 in. of insulation on the outside. The convective coefficient for the inside steam surface of the pipe is estimated as hi = 1000 btu/h.ft2. OF, and the convective coefficient on the outside of the lagging is estimated as ho = 2 btu/h. ft2.0F. The mean thermal conductivity of the metal is 26 btu/h.ft.0F and 0.064 W/m.K or 0.037 btu/h.ft.0F for the insulation. Calculate the heat loss for a unit length in ft of pipe using resistances if the surrounding air is at 800F.
