A 1 lbm/s fluid enters a machine at 170 m/s, 800 kPa, and with a specific volume of 0.3 m³/kg. The radiation heat loss is 25 kJ/kg. The internal energy decreases 485 kJ/kg. If the fluid leaves at 330 m/s, 138 kPa, and 0.95 m³/kg, determine the work done by the fluid in kW.

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing. 

Question

Note: don't mind the shaded answer, I just accidentally click that

A 1 lbm/s fluid enters a machine at 170 m/s, 800 kPa,
and with a specific volume of 0.3 m³/kg. The radiation
heat loss is 25 kJ/kg. The internal energy decreases 485
kJ/kg. If the fluid leaves at 330 m/s, 138 kPa, and 0.95
m3/kg, determine the work done by the fluid in kW.

hand written plz Answer the following questions using the information provided in this unit. Know and Understand 1. True or False? The primary purpose of section views is to help feature exterior detail without using hidden lines. For the next three terms, match the three types of lines to the three descriptions. Answers are used only once. 2. Cutting-plane line 3. Section line 4. Short break line A. Not exclusive to section views, but needed for broken- out sections. B. Drawn thick in a view adjacent to the section view. C. Drawn thin, and usually continuous, but sometimes dashed. 5. Of the following, which is not a type of section view featured in this unit? A. Full B. Half C. Quarter D. Offset 6. True or False? The preferred dividing line between the two halves of a half-section view is the visible line. 7.
