(a) A length of brass piping is 30 m long at a temperature of 18°C. When hot water flows through it the temperature of the pipe rises to 70°C. Determine the length of the hot pipe if the coefficient of linear expansion for brass is 18 x 10-6 K-¹.
Is the continuity equation applicable for steam despite being compressible fluid?
An insulated vertical cylindrical vessel of cross- sectional area A = 0.12 m² contains 20 mol of He gas at To = 300 K and Po= 0.5 bar. It is capped by a movable piston of mass m = 150 kg supported from the ceiling by a wire. The top of the vessel is open to the atmosphere (Patm= 1 bar, Tatm= 300K). The wire is cut and the weight falls and com- presses the gas.

Comment on whether your solution takes into account the inevitable oscillations of the piston around its equilibrium position before it comes to rest. mut Ispl (b) After a long time, the He gas thermally equilibrates with the environ- ment by heat transfer through the piston. How much heat is exchanged with the environment during this process? Helium can be considered an ideal gas at all conditions of interest, with C₁=3R/2. INST

Define elementary two dimensional flows with figures.
An incompressible fluid flows over a flat plate with zero pressure gradient. The boundary layer thickness is 1mm at a location where the Reynolds number is 1000. If the velocity of the fluid alone is increased by a factor of 4, then the boundary layer thickness at the same location, in mm will be 415
