Select the proper size steel tube for a flow rate of 19 gpm and an operating pressure of 1550 psi. the maximum recommended velocity is 15 ft/min and the tube material is sae 1010 dead soft cold-drawn steel having a tensile strength of 95,000.

The power source in a certain welding setup generates 3500w that is transferred to the low carbon steel work with a heat transfer factor of 0.85. the melting factor in the operation is 0.45. a continuous fillet weld is to be made with a cross-sectional area of 23 mm2 determine the travel speed at which the welding can be accomplished.
