in turbofan engine, the thrust is only generated by the fan, and work generated by the turbine core is only developed to move the fan and compressor of the entire turbine

true or false

the air fuel ratio used in jet engine is very small

true or false

the definition of thermodynamics is the study of the behavior of gases and heat

true or false

Expert Solution

Solutions:

Question:

In turbofan engine, the thrust is only generated by the fan, and work generated by the turbine core is only developed to move the fan and compressor of the entire turbine.

true or false

Answer: False

Explanation:

Because thrust in the turbofan engine is generation not only by the fan but also the engine. Engine produces thrust because of bypass of air from the core of the engine.

Question:

The air fuel ratio used in jet engine is very small

true or false

Answer : False

Explaination :

In jet engine the excessive air is used to burn the fuel so, generally the air fuel ratio in jet engine is very high. For example, 50:1, 130:1. The excessive air makes the air fuel mixture very lean.

Question :

The definition of thermodynamics is the study of the behavior of gases and heat.

true or false

Answer: True

Explanation:

Thermodynamic is the study of heat and convert heat (of gases, steam) into the power. So, the given statement is true.

1. For airflow through a fan, the mechanical energy balance with fan work along with conservation of mass are: -W(dot)fan=sum((m(dot)_exit)*(e_exit)) - sum((m(dot)_inlet)*(e_inlet)) so... 0=sum(m(dot)_exit) - sum(m(dot)_inlet) Using the mechanical energy balance and conservation of mass, show that the theoretical fan power added to the air is flow rate multiplied by the pressure rise: W(dot)fan=?*?*P

Two Way ANOVA A mechanical engineer is studying the thrust force developed by a drill press. He suspects that the drilling speed and the feed rate of the material are the most important factors. He selects four feed rates and uses a high and low drill speed chosen to represent the extreme operating conditions. He obtains the following results. (A) Feed Rate (B) Drill Speed 0.015 0.030 0.045 0.060 125 2.70 2.45 2.60 2.75 2.78 2.49 2.72 2.86 200 2.83...

A rocket has a mass of 1.40×04 kg and its engine has a thrust of 200×105 N. If its engines fire in the vertical direction for 1 min starting from rest, to what vertical height would it rise in the absence of air resistance? (To simplify things, assume the mass is constant. However, in reality the mass of rockets decreases substantially while rising)
