Steam at 300 psia and 800 $^\circ$F steadily enters a nozzle whose inlet area is 0.2 ft$^2$. The mass flow rate of steam through the nozzle is 10 lbm/s. Steam leaves the nozzle at 200 psia with a velocity of 900 ft/s. Heat losses from the nozzle per unit mass of the steam are estimated to be 1.2 Btu/lbm. Determine the inlet velocity $q_{out}$ = 1.2 Btu/lbm $P_1$ = 300 psia $T_1$ = 800$^\circ$F $A_1$ = 0.2 ft$^2$ Steam m = 10 lbm/s $P_2$ = 200 psia $V_2$ = 900 ft/s

Show your work. Use correct numbers of significant figures and include your units. Problem #1 (show your work) (25 pts): A snowmobile moves according to the velocity-time graph shown in the drawing. It starts from the origin at $t = 0$ and moves along the positive x-axis A (8 pts) What is the displacement of the snowmobile from $t = 0$ s to $t = 40$ s? B. (8 pts) What is the average velocity of the snowmobile during the interval $10 \le t \le 40$ seconds? C. (3 pts) In each of the segments A, B, C and D, state whether the snowmobile is accelerating, decelerating, or not accelerating D. (6 pts) What is the average acceleration of the snowmobile during segment B?
