What is the difference between direct injection and indirect injection?
Expert Solution & Answer
To determine
The difference between direct and indirect injections.
Explanation of Solution
The differences between direct and indirect injections are shown in below table.
| S.No. | Direct injection | Indirect injection |
| 1 | The fuel is directly injected into the cylinder. | The fuel is injected into the cylinder through a pre-chamber by a narrow opening. |
| 2 | The first combustion occurs in the cylinder where the piston experiences a depression. | The first combustion occurs in the pre-chamber. |
| 3 | More efficient and more noise. | Less efficient and less noise. |

Steam flows steadily through a turbine at a rate of 45,000 lbm/h, entering at 1000 psia and 900°F and leaving at 5 psia as saturated vapor. If the power generated by the turbine is 4.1 MW, determine the rate of heat loss from the steam. The enthalpies are h1 = 1448.6 Btu/lbm and h2 = 1130.7 Btu/lbm.
The rate of heat loss from the steam is Btu/s.

In an effort to cool a 12- fluid-oz drink in a can, a person grabs the can and starts shaking it in the iced water of the chest at 32°F. Using the properties of water for the drink, determine the mass of ice that will melt by the time the canned drink cools to 37°F. The density and specific heat of water at the average temperature of (85+37)/2 = 61ºF are ρ = 62.3 lbm/ft3 and cp = 1.0 Btu/lbmºF (Table A-3E). The heat of fusion of water is 143.5 Btu/lbm.
