National Diploma in Mechanical Engineering Section A: COMPULSORY Answer ALL questions 1-12 1. A resistance temperature device has a resistance R0 = 100 Ω at 0o C. If the resistance RT = 197.7 Ω in an oil bath‚ what is the temperature of the oil in the bath‚ given that RT = R0(1+αT)? Take R0 = 100 Ω R0 = resistance at 0o C α = 3.9083 x 10-3 /o C (2 marks) NDE Thermodynamics and Heat Transfer Exam 2008 Name: _______________________________________ Read all the instructions before starting Do

in the atmosphere; this is how earth keeps herself warm. The sun’s ray goes through the Earth’s atmosphere and loses most of its energy as the wave hits the earth’s surface so that its warmth can’t go back through the shield of gases‚ thus the insulation for Earth is created. About 50% of thermal energy from the sun is absorbed at the top of the atmosphere‚ and since little or no heat can escape after collision with Earth‚ the greenhouse gas is a natural blanket around the earth. However‚ too much
