The local atmospheric pressure is 88 kPa. Now‚ heat is transferred to refrigerant-134a until the temperature is 15°C. Determine (a) the final pressure‚ (b) the change in the volume of the cylinder‚ and (c) the change in the enthalpy of the refrigerant-134a. 3. Determine the specific volume of superheated

FREESTUDY HEAT TRANSFER TUTORIAL 2 CONVECTION AND RADIATION This is the second tutorial in the series on basic heat transfer theory plus some elements of advanced theory. The tutorials are designed to bring the student to a level where he or she can solve problems ranging from basic level to dealing with practical heat exchangers. On completion of this tutorial the student should be able to do the following. • • Explain the use of the surface heat transfer coefficient. • Explain

Sam Wood‚ a respected police officer in Wells‚ South Carolina‚ patrols the city every night. One night‚ after stopping at his usual diner for a snack‚ and discussing Negros unfavorably with Ralph‚ the night counterman‚ Sam finds a body in the middle of the highway. He reports the body‚ which is soon tentatively identified as that of Maestro Enrico Mantoli‚ the conductor and lead organizer of the city’s upcoming music festival. Bill Gillespie‚ the chief of police‚ is notified‚ and after his arrival

Title: Heat Treatment of Ferrous Objective: To determine the effect of heat treatment on mechanical properties of 1050 Steel. To reveal the microstructures of 1050 steel during heat treatments. Abstract In this experiment‚ we observed how the properties of plain carbon steel vary with the heat treatment condition. We prepared six different samples in three different heat treatment configurations and performed hardness tests on them by using the Rockwell tester and observed the microscopic

Until the 1960s‚ the radio was the only significant electronics in an automobile. All other functions were entirely mechanical or electrical‚ such as the starter motor and the battery charging systems. There were no “intelligent safety systems‚” augmenting the bumper and structural members to protect occupants in case of accidents. Seat belts‚ introduced in the early 1960s‚ were for improving occupant safety and actuated completely mechanically. The driver or one of several mechanical control

Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before
