Water at high pressure and properties p1, v1, u1, hi and mass m1 is in a container and part of the water with mass me and properties pe, ve, ue, he exits the container after "pushing" a turbine. eventually, the pressure drops and the process stops. at the end of the process, the water in the container has properties p2, v2, u2, h2. if no heat crossed the boundaries of the container, what is the total work w done by the water to power the turbine?

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.
