Wet steam at 15 bar is throttled adiabatically in a steady-flow process to 2 bar. The resulting stream has a temperature of 130°C. What are the temperature and quality of the wet steam? Calculate the change of entropy of the steam as a result of the process. It is important to note that a throttling process is where the change of enthalpy is zero (that is, AH = 0). Temperature ~ 198 °C and the quality of 96.76%. AS = 0.8708 kJ/kg-K

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
