In a certain industrial process, it is known that the temperature of one of its stages varies between 10°C and 50°C. The measuring instrument used to measure this temperature has its measurement range from -50°C to 50°C, with a dead zone of 1%. In view of the above, it is stated that the measuring instrument (A) will not show temperature variations lower than or equal to 0.5 °C. (B) will not show temperature variations lower than or equal to 1 °C. (C) is not suitable for the measurement for which it is used, since it may present distortions in the measurement of the temperature if it is between 49 C and 50 C. (D) measures, although not reliably accurate,temperatures ranging up to 0.5° C beyond its range of nominal measure. (E) measures, although unreliable in accuracy, tem- temperatures ranging up to 1° C beyond their rating range nominal measure.

2.55 A long, 1-cm-diameter electric copper cable is embedded in the center of a 25-cm-square concrete block. If the outside temperature of the concrete is 25oC and the rate of electrical energy dissipation in the cable is 150 W per meter length, determine temperatures at the outer surface and at the center of the cable.
1.60 Two electric resistance heaters with a 20 cm length and a 2 cm diameter are inserted into a well-insulated 40-L tank of water that is initially at 300 K. If each heater dissipates 500 W, what is the time required for bringing the water temperature in the tank to 340 K? State your assumption for your analysis.
During a picnic on a hot summer day, the only available drinks were those at the ambient temperature of 90°F. In an effort to cool a 12-fluid-oz drink in a can, which is 5 in high and has a diameter of 2.5 in, a person grabs the can and starts shaking it in the iced water of the chest at 32°F. The temperature of the drink can be assumed to be uniform at all times, and the heat transfer coefficient between the iced water and the aluminum can is 30 Btu/h·ft2·°F. Using the properties of water for the drink, estimate how long it will take for the canned drink to cool to 40°F.
Hi, can you help me to answer this question using the first law of thermodynamics formula to explain this event? On a hot summer day, a student turns his fan on when he leaves his room in themorning. When he returns in the evening will the room be warmer or cooler than theneighborouing rooms ? Explain your answer using the first law of thermodynamics.Assume ALL doors and windows are kept closed.
There is a cylindical piece of nickel, that is 5 cm in diameter and 10 cm in length, that is initially at 20 degrees Celcius before being dropped into a hot fluid that is at 190 degrees Celcius. Determine the amount of heat gained by the cylinder until its temperature rises to 80 degrees Celcius. Show details in calculations and specify values retrieved from property tables.
