Topic: First order ODEsA hot object is allowed to cool in air of constant temperature Tm. The object's temperature was initially at 170°C and cooled to 90°C in 10 minutes. Knowing that the material has a temperature decay constant of k=0.075/min, determine the temperature of the air.Answer is Tm = 18.38°CPlease show me how to get this answer
In a double-glazed window, the panes of glass are separated by 1.0 cm and the space is filled with a gas with thermal conductivity 24 mW K−1 m−1. What is the rate of transfer of heat by conduction from the warm room (28 °C) to the cold exterior (−15 °C) through a window of area 1.0 m2? You may assume that one pane of glass is at the same temperature as the inside and the other as the outside. What power of heater is required to make good the loss of heat?
Posting it second time . Answer all else dont answer - You are using a silver spoon to stir water that just started boiling so that you can achieve a more even heat distribution in your water. The spoon is partially immersed in boiling water and a thermometer in your kitchen reads 27 °C. The handle of the spoon has a cross section of 2mm × 1cm and extends 15 cm in the air from the free surface of the water. The heat transfer coefficient at the exposed surfaces of the spoon handle is 3 W/m2 ×K. Part A : Determine the temperature difference across the exposed surface of the spoon handle. Follow the problem-solving guide on the front page. At the minimum, your analysis should answer the following questions providing detailed justifications:-What are the modes of heat transfer that the spoon is exposed to? -Is this a time dependent or steady state problem? Why or why not?-Is this a 1-D, 2-D or 3-D problem? Why or why not?- What is the thermal conductivity of the material?- The heat…
