Chapter 17, Problem 1R
What effect does torch angle have on the shielding gas protective zone?
Expert Solution & Answer
To determine
Effect of torch angle on shielding gas protective zone.
Explanation of Solution
Torch angle position is an important parameter for good quality of gas tungsten weld. Perpendicular position of the torch is the ideal position for good quality of weld. Torch needed to hold near about perpendicular as much as possible. For better visibility torch can angled about

Liquid hexane flows through a counter flow heat exchanger at 5 m3/h as shown in Figure E5.5.The hexane enters the heat exchanger at 90°C. Water, flowing at 5 m3/h, is used to cool the hexane.The water enters the heat exchanger at 15°C. The UA product of the heat exchanger is found to be2.7 kW/K. Determine the outlet temperatures of the hot and cold fluids and the heat transfer ratebetween them using LMTD method.
Determine the fluid outlet temperatures and the heat transfer rate for the counter flow heatexchanger described in Problem 3 using the ε-NTU model. Assume that the properties can beevaluated at the given fluid inlet temperatures.
