A stream of air at 35°C and a gauge pressure of 0.5 atm (Stream 1) flows into a pipe passing through a heater, emerges at 87°C and 0.2 atm (gauge), and splits into two streams. Stream 2 passes out of the system, and Stream 3 goes through another heater and emerges at 180°C and 0.1 atm (gauge). Flowmeters mounted in all three streams show readings of 3120 L/min (Stream 1), 1940 L/min (Stream 2), and 3420 L/min (Stream 3). Show that the system is not functioning properly. Speculate on several possible causes of the malfunction, and state how you would check each one.

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.
