A GTAW operation is performed on low carbon steel, whose unit melting energy is 10.8 J/mm3. The welding voltage is 22 volts and the current is 149 amps. The heat transfer factor is 0.65 and the melting factor is 0.66. If filler metal wire of 3.9 mm diameter is added to the operation, the final weld bead is composed of 57% filler metal and the rest base metal. If the travel speed in the operation is 4 mm/sec, determine the feed rate (mm/sec, 1 decimal point) at which the filler wire must be supplied.

6-22 Water flowing through a horizontal pipe is accelerated by using cotton ball one day, and it is about to change it upward by 0 = 45°. Elbow releases water into the atmosphere. Elbow's cross-sectional area is 150 cm² at the inlet and 25 cm² at the outlet. The height difference between the center of the inlet and outlet is 40 cm. The mass of water in Elbow and Elbow is 50 kg. Calculate the force required to hold Elbow in place. The momentum flux correction factor is 1.03 at both the inlet and outlet.

A company produces a special new type of TV. The company has fixed costs of $452,000, and it costs $1100 to produce each TV. The company projects that if it charges a price of $2400 for the TV, it will be able to sell 850 TVs. If the company wants to sell 900 TVs, however, it must lower the price to $2100. Assume a linear demand. If the company sets the price at $3600, how much profit can it earn? It can expect to earn/lose $ (Round answer to nearest dollar.)
