Solutions to Problems (Übungen) to Lecture-1 of Lecture Series “Heat Transfer – 1” Institut für Energieverfahrenstechnik und Brennstofftechnik‚ TU Clausthal‚ SS 2005 1.1 A heat rate of 5 kW is conducted through a cross section area of 20 m2 and thickness of 3 cm. If the inner (hot) surface temperature is 600ºC and the thermal conductivity of the material is 0.5 W/mK‚ what is the outer surface temperature? Solution: Tout = 585 °C 1.2 The heat flux through a wood slab 50 mm thick‚ whose inner and outer

Aim: i) To find the relationship between supplied energy and change in temperature of water. ii) To find the specific heat capacity (SHC) of water. Hypothesis: As time increases so does the temperature since the water is exposed to the heated wire for a longer period of time. Variables: The Dependent Variable is the temperature of the water‚ and since the Energy is calculated using temperature it is a dependent variable as well. The constant variables are the voltage and current. Theory:

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

To what extent does heat exposure affect an athlete? Heat exposure is a factor that is essential to be considered by athletes to maximise performance level. Researchers have investigated that excessive heat exposure or exercise hyperthermia has detrimental effects on exercise physiology. Little is understood regarding the effects of hyperthermia and how heat exposure affects the body. Localised heat studies using water immersion to increase muscle temperature have been conducted to investigate the

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

Heat Stress in the Work Place! Eastern Kentucky University Heat Stress is the exposure to extreme heat or working in hot environments. Workers who are exposed to this may be at risk of heat stress. Heat Stress can result in occupational illnesses and injuries. “Heat stress can result in heat stroke‚ heat exhaustion‚ heat cramps‚ or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms‚ fogged-up safety glasses‚ and dizziness. Burns may

The theory of personal space proposes that you and I feel uncomfortable when others get too close in certain situations. This discomfort can‚ says the theory‚ be measured by increased heart rate‚ blood pressure or skin perspiration. The research problem is that to measure these things we have to hook a subject up to some device‚ and they thus know they are being studied. Their behavior might not be natural. To test the theory and solve this problem‚ the following was done: A study by Middlemist

FORMAL REPORT ON HEAT CAPACITY RATIOS OF GASES ABSTRACT This report discusses an investigation of the heat capacities of Helium‚ Nitrogen‚ and Carbon Dioxide. To accurately determine experimental values for the heat capacity of each gas‚ the heat capacity ratio was calculated from measurements of the speed of sound in each gas. An apparatus designed to measure the wavelength and frequency of sound waves in each gas was used to determine the speed of sound as a frequency was passed through each
