A certain brand of hotdog cooker works by applying a potential difference of 146 V across opposite ends of a hot dog and allowing it to
cook by means of the thermal energy produced. The current is 12.8 A, and the energy required to cook one hot dog is 60.8 kJ. If the
rate at which energy is supplied is unchanged, how long will it take to cook three hot dogs simultaneously?

- 4. An incandescent lamp has a tungsten filament whose resistance is 96 ohm at its operating temperature of 2900°C. Calculate the filament resistance when the lamp is disconnected from the electric source under which conditions the temperature is 24°C.arrow_forwardA heat pump supplies heat energy to a house at the rate of 140,000 kJ/h when the house is maintained at 25°C. Over a period of one month, the heat pump operates for 100 hours to transfer energy from a heat source outside the house to inside the house. Consider a heat pump receiving heat from two different outside energy sources. In one application the heat pump receives heat from the outside air at 0°C. In a second application the heat pump receives heat from a lake having a water temperature of 10°C. If electricity costs $0.105/kWh, determine the maximum money saved by using the lake water rather than the outside air as the outside energy source.arrow_forwardA certain parallel-plate capacitor is filled with a dielectric for which K = 6.50.

- One of the most common appliances used on a daily basis is the hair dryer. A hair dryer is basically a duct in which a few layers of electric resistors are placed. A small fan at the back of the device pulls the air in and forces it through the resistors where it is heated (see Fig. 1). The power consumed by the heating elements (i.e. electric resistors) of the hair dryer is 1258 Watts. Air enters the hair dryer at 95 kPa and 25°C and leaves at 50°C. The cross-sectional area of the hair dryer at the exit is 55 cm². The power consumed by the fan is 2 Watts and the heat loss through the walls of the hair dryer is 5 Watts. By clearly stating your assumptions throughout, 1.Analytically describe the Fluid Mechanics and Thermodynamics working principles of the hairdryer; 2. Provide a schematic diagram of the hair dryer clearly indicating the system's boundaries, mass flows and energy/heat flows; 3. Determine the volumetric flow rate of the air at the inlet; 4. Determine the velocity of the…arrow_forwardReplacing incandescent lights with energy-efficient fluorescent lights can reduce the lighting energy consumption to one-fourth of what it was before. The energy consumed by the lamps is eventually converted to heat, and thus switching to energy-efficient lighting also reduces the cooling load in summer but increases the heating load in winter. Consider a building that is heated by a natural gas furnace with an efficiency of 80 percent and cooled by an air conditioner with a COP of 3.5. If electricity costs $0.12/kWh and natural gas costs $1.40/therm (1 therm = 105,500 kJ), determine if efficient lighting will increase or decrease the total energy cost of the building (a) in summer and (b) in winter.arrow_forward
