HEAT AND MASS TRANSFER PYQ SOLUTION | Convection, Boiling & Condensation

Описание: 📘 Heat Transfer Numericals | Convection, Boiling & Condensation | Mechanical Engineering

In this video, we solve important numericals from the topic of Convection Heat Transfer, Boiling, and Condensation. This will help students understand step-by-step problem solving for university exams, GATE, ESE, and competitive exams.

problem statement - Light oil in a tank is maintained at a temperature of 35°C by means of
steam condensing in a 3.5 cm diameter coil immersed in the tank. The
steam maintains the coil surface temperature at 95°C. Assuming the coil
pipes to be horizontal cylinder, determine the outside surface heat transfer
coefficient. The properties of oil at 65°C are density, ρ = 855kg / m3,
Specific heat Cp
= 2005 J/kg K, K = 0.133W/mK, dynamic viscosity
μ=0.00827 Ns/m2, β =7.2 × 10–4 K–1.
