The internal steam pressure in a boiler is 4 N/mm². The thickness of the boiler plate is 1.5 cm and the boiler may be assumed to be a thin-walled vessel. The permissible tensile stress is 130 N/mm². The efficiencies of the longitudinal and circumferential joints are 90% arid 35% respectively. Find the maximum diameter of the boiler. Comment on the assumption of the boiler being a thin-walled vessel.

A brass boiler has a base area of $0.15 \mathrm{~m}^{2}$ and thickness $1.0 \mathrm{~cm} .$ It boils water at the rate of $6.0 \mathrm{~kg} / \mathrm{min}$ when placed on a gas stove. Estimate the temperature of the part of the flame in contact with the boiler. Thermal conductivity of brass $=109 \mathrm{~J} \mathrm{~s}^{-1} \mathrm{~m}^{-1}$ $\mathrm{K}^{-1}$; Heat of vaporisation of water $=2256 \times 10^{3} \mathrm{~J} \mathrm{~kg}^{-1}$.
The fluid temperature on the boiler side on any plane in a heat exchanger is given as 100 C degree. and the temperature on the pipe side as 20 C degree. As the wall separating hot and cold fluids is very thin, the conductor resistance can be ignored. There is no sedimentation in the system. Calculate the wall temperature for cases where the heat transfer coefficients on both sides are equal, the heat transfer coefficient on the pipe side is 3 times that of the boiler side, the heat transfer coefficient on the pipe side is equal to half of the boiler side and the limiting coefficient is the limiting coefficient on the pipe side. Derivation must be done before using equations. Thanks.
