Consider an enclosure formed by three surfaces having the following values of shape factors, emissivities and temperatures Surface 1 i.e. curved cylindrical has an emissivity 0.75 and temperature 800 K Surface 2 i.e. closing disc has an emissivity 0.8 and temperature 700 K Surface 3 i.e. closing disc has an emissivity 0.8 and temperature 700 K The closing flat discs are 25 mm in diameter and they have interspacing distance equal to 100 mm. If the shape factor between these two identical discs is 0.05, calculate the net rate of radiant heat flow from the curve surface to each of the closing end surface
Statement : According to the officials, paucity of funds with the organisation has led to the pathetic condition of this brilliant architectural structure.

Courses of Action :
I. A new architectural structure for the building should be designed.
II. The reasons for the poor condition of the structure should be found out.
III. Grant should be given to improve the condition of the structure.
A finned surface consists of root or base area of 1m2 and fin surface area of 2m2. The average heat transfer coefficient for finned surface is 20W/m2K effectiveness of fins provided is 0.75. If finned surface with surface with root or base temperature of 50°C is transferring heat to fluid of 30°C, then the rate of heat transfer without using fin is _______
A structure is supported by a triangular structure which can withstand a certain weight in a particular configuration depending upon their surface area. The structure which is to be balanced is a square and triangles are kept on their base in a line such that the total length of the bases is equal to the side of square. There are total 15 such lines with some space in between and each line has 10 triangles. The square, weighing 50 kg and 10 m side, is balanced 3m above the ground. What is weight on per unit area of triangles?
