Pressurized water (pin = 10 bar, Tin = 110°C) enters the bottom of an L = 12-m-long vertical tube of diameter D = 110 mm at a mass fow rate of m = 1.5 kg/s. The tube is located inside a combustion chamber, resulting in heat transfer to the tube. Superheated steam exits the top of the tube at pout = 7 bar, Tout = 600°C. Determine the change in the rate at which the following quantities enter and exit the tube:

a. The combined thermal and fow work.
b. The mechanical energy
c. The total energy of the water.
d. determine the heat transfer rate, q.

What precautions should you take to prevent injuries when dealing with heavy loads?

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

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.
