Choose the appropriate answer(s) for the following questions: 1- At steady state condition, the temperature distribution
questions: 1- At steady state condition, the temperature distribution in a large thin plate with uniform surface temperature will be: - Logarithmic b- Hyperbolic - Parabolic d. Linear ii- Hent is transferred from a hot fluid to a cold one through a plane wall of thickness (). surface area (A) and thermal conductivity (k). The thermal resistance is: 1-1/A (1/h + 5k + 1/h) b- Ax(1/h+k+1/h) - 1/A (h+k+h) de Ax (h+k+1/h) - A pipe carrying steam at 215.75 degree Celsius enters a roon and some heat is gained by surrounding at 27.95 degree Celsius. The major effect of heat loss to surroundings will be due to: - Conduction b- Convection - Radiation d-Both conduction and convection ir The unit of thermal diffusivity is: a- m/hr-K b- keal/m-hr Com/hr d-m/hr-K - In respect to the critical radius of insulation: a- There is more heat loss i.c. conductive b. There occurs a decrease in heat flux c- Heat loss increases with addition of insulation d. Heat loss decreases with addition of insulation vi- For an insulation to be properly effective in restricting heat transmission, the radius re should be: a- Greater than critical radius b. Less than critical radius - Equal to critical radius d- Greater than or equal to critical radius za z vii- Which one of the following is having the lowest thermal conductivity? a- Glass b- Wool C- Saw dust d- Glass wool
