3. (20 pts) In the Carnot engine (refer to the figure in question 2), an ideal gas undergoes a cycle of isothermal expansion (A → B), adiabatic expansion (B → C), isothermal compression (C → D), and adiabatic compression (D → A). All processes are assumed to be reversible. The volumes at the points are given that 2VA=VB and VC=2VD. Th is 650 °C and Tc is 30 °C. (1) Calculate the amount of heat added to one mole gas...

The amount of lateral expansion (mils) was determined for a sample of n=20 pulsed-power gas metal ore welds used in LNG ship containment tanks. The resulting sample standard deviation was s=2.45 mils. Assuming normality, derive (give answers to 3 places past decimal) : a) a 95% confidence interval for 02 upper limit = lower limit = A Tries 0/5 a) a 95% confidence interval for o upper limit = lower limit = Tries 0/5
