A chromel–constantan thermocouple measuring the temperature of a fluid is connected by mistake with copper–constantan extension leads (such that the two constantan wires are connected together and the copper extension lead wire is connected to the chromel thermocouple wire). If the fluid temperature was actually 250 C and the junction between the thermocouple and extension leads was at 90 C, what e.m.f. would be measured at the open ends of the extension leads if the reference junction is maintained at 0 C? What fluid temperature would be deduced from this (assuming that the connection error was not known)?
A copper rod of 30 kg initially at the temperature of 300 °C needs to be immersed and fitted tightly into a ABA alloy ring with inner diameter 30.0015 mm found in tank of 100 liters water of 25 °C.

The polished stainless steel pot is cylindrical, 20 cm in diameter and 14 cm high, with a tight-fitting flat cover. The air temperature in the kitchen is about 25 ° C. State any assumptions you make in deriving your estimates
1. A steel sphere 3” in diameter heated to 600oF, is to be cooled by immersion in an oil bath at 100oF. Calculate the average temperature of the sphere a) 10 sec and b) 6 min after immersion. For steel, k = 26Btu/ft-h-oF;  = 486lb/ft3 ; Cp = 0.11Btu/lboF.
A mass of ice at -4°C is needed to cool 115 kg of vegetables in a bunker for 24 hours. The initial temperature of the vegetables is assumed to be 29°C. It is also assumed that, within the 24-hr period, the average temperature inside the bunker is 7°C. If the heat gained per hour in the bunker is 30% of the heat removed to cool the vegetables from 29°C to 7°C, what would be the required mass of ice in kg? Use: Specific heat of water 4.2292 kJ/kg-°C Specific heat of ice 1.9387 kJ/kg °C Specific heat of vegetables 3.35 kJ/kg-°C
A 10 cm outer diameter pipe carrying saturated steam at a temperature of 195C is lagged to 20 cm diameter with magnesia and further lagged with laminated asbestos to 25 cm diameter. The entire pipe is further protected by a layer of canvas. If the temperature under the canvas is 20°C, find the mass of steam condensed in 8 hrs on a 100m length of pipe and interface temperature. Take thermal conductivity of magnesia as 0.07 W/m – K and that of asbestos as 0.082 W/m – k. Neglect the thermal conductivity of the pipe material. The latent heat of steam for given conditions can be taken as 1951 kJ/kg–K.

1. The boiling temperature of water is 100 °C. If you put boiling water in a mugplaced at the table top, you observed that after some time the water cools down,decreasing the temperature of water in the mug. Why is this so? Explain using theZeroth Law of Thermodynamics. What happens to objects when temperature increases? For instance, a jar cover an be removed by putting the cover in hot water. Why is this so?
Two friends, Jack and Jill, sit down to talk and enjoy a cup of coffee. When the coffee is served, Jack immediately adds a tablespoon of cream to his coffee. Jill, occupied with the discussion, waits 10 minutes before adding a tablespoon of cream, which has been kept at a constant temperature. The two friends then begin to drink their coffee. Who has the hotter coffee at that time? Assume that the cream is cooler than the air and justify your answer using Newton’s law of cooling. Please help solve this problem! Thank you!
