Answer:
Fuel oil is mixed with a proper portion of compressed air
Explanation:
A gas turbine has three main part, which are
- combustion chamber
- air compressor
- power turbine
The combustion chamber is responsible for mixing fuel with a proper portion of compressed air.
The air compressor supplies air in sufficient quantity to satisfy the requirements of the combustion chamber
The power turbine produces the power to drive the air compressor.
Answer:
a. closer to 20∘C
Explanation:
= mass of pallet = 50 g = 0.050 kg
= specific heat of pallet = specific heat of iron
= Initial temperature of pellet = 200 C
= mass of water = 50 g = 0.050 kg
= specific heat of water
= Initial temperature of water = 20 C
= Final equilibrium temperature
Also given that
Using conservation of energy
Energy gained by water = Energy lost by pellet
hence the correct choice is
a. closer to 20∘C
(a) We will use the equation v = u + at
Initial velocity u = 5.00 m/s
Acceleration a = 0.0600 m/s²
time = 8 min = 8 x 60 = 480 s
Final velocity
= u + at
= 5.00 + 0.0600(480)
= 33.8 m/s
The final velocity is 33.8 m/s
