Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Thermodynamics Answer the following problem with complete solutions. Write legibly A gas goes through the following thermodynamic processes: A to B: constant-temperature compression; B to C: constant-volume cooling; C to A: constant-pressure expansion.

HW4 EX1: An automobile moving over a rough road (Fig. 1.64) can be modeled considering (a) weight of the car body, passengers, seats, front wheels, and rear wheels; (b) elasticity of tires (suspension), main springs, and seats; and (c) damping of the seats, shock absorbers, and tires. Develop three mathematical models of the system using a gradual refinement in the modeling process. FIGURE 1.64 An automobile moving on a rough road. EX2 1.5* The consequences of a head-on collision of two automobiles can be studied by considering the impact of the automobile on a barrier, as shown in Fig. 1.65. Construct a mathematical model by considering the masses of the automobile body, engine, transmission, and suspen- sion and the elasticity of the bumpers, radiator, sheet metal body, driveline, and engine mounts.

A house, for cooling purposes, consists of two zones: the attic area zone A and the living area zone B (see below figure). The living area is cooled by a 2-ton air conditioning unit that removes 29,000 Btu/hr. The heat 2 hr A 1 capacity of zone B is °F per thousand Btu. The time constant for heat transfer between zone A and the 4 29,000 Btu/hr outside is 2 hr, between zone B and the outside is 4 hr, and between the two zones is 4 hr. If the outside 4 hr 4 hr temperature stays at 110°F, how warm does it eventually get in the attic zone A? B It eventually gets to be °F in the attic zone A. (Type an integer or decimal rounded to the nearest hundredth as needed.)
A certain ideal gas (unknown) inside a close piston-cylinder assembly undergoes a set of processesthat composed of Isothermal expansion from State point 1 to state point 2, Isometric heat rejectionfrom state point 2 to state point 3, and Isentropic compression from state point 3 back to the initialcondition. If the maximum pressure is 3000kPa and maximum and minimum volume is 200cm3and50cm3, analyze the problem and perform the following:a. Draw and label the graph of this set of processes in the P-V and T-S diagram showing the statepoint numbers and energy directions.b. From the known ideal gases as shown in Table 1.0, select the best suited ideal gas to attain theprocesses stated if the lowest pressure is limited to 629.8kPa. Assume a constant specific heat.c.
