An aluminum cylindrical tank having a total weight of 130kN including its contents is supported by 4 wooden posts arranged in such a way that the foundation will form a square having a side of 3m. The wooden posts is battered at 1 horizontal is to 5 vertical. Assume unsupported length of 3.5m. The tank is subjected to a wind load of 200kN acting at a distance 7m from the concrete foundation treating the posts to be hinged on both ends. The posts has an allowable compressive stress parallel to grain at 15.8MPa and a modulus of elasticity of 9780MPa.

a. Compute the actual reaction on the wooden posts based on the loads.

b. If the posts have an upper diameter D1 of 100mm and lower diameter D2 of 250mm, are the posts enough to carry the given loads?

c. If not, recommend a size to support the loads.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
