Experiment 4 OBJECT: - To determine the surface heat transfer coefficient for a vertical tube losing heat by natural convection. INTRODUCTION: - When a hot body is kept in still atmosphere, heat is transferred to the surrounding fluid by natural convection. The fluid layer in contact with the hot body gets heated; rise up due to the decrease in its density and the cold fluid rushes in to take place. The process is continuous and the heat transfer takes place due to the relative motion of hot cold fluid particles. APPARATUS: -  SPECIFICATIONS: - Diameter of cylinder (d) = 38 mm Length of cylinder (L) = 500 mm Thermal conductivity of tube material (k) = W/mK Perimeter of cylinder = m Cross section area of cylinder = m2 FORMULAS: - The heat transfer coefficient is given by: where, h = Average surface heat transfer coefficient (W/ m 2 K) q = Heat transfer rate (Watts) A s = Area of heat tra...

Founded by J. R. D. Tata in 1932 i.e. on 15 October 1932 as Tata Airlines Tata Airlines became a public limited company on 29 July 1946 under the name Air India. On 8 June 1962, the airline's name was officially truncated to Air India. In 1971, the airline took delivery of its first Boeing 747-200B named Emperor Ashoka. In 1994 the airline was registered as Air India Ltd.  In 2007, the Government of India announced that Air India would be merged with Indian Airlines.
