5. During the flight, the air speed of a turbojet engine is 250 m/s. The ambient air temperature is - 14°C. The exhaust gas temperature at the outlet of the nozzle is 610°C. Corresponding enthalpy values for air and exhaust gas are respectively 250 kJ/kg and 900 kJ/kg. The fuel-air ratio is 0.0180. The chemical energy of the fuel is 45 MJ/kg. Heat loss from the engine is 21 kJ/kg of air. Calculate the velocity of the exhaust gas in m/s from the jet.

The answer is one of the options below please solve carefully and circle the correct option Please write clear .

QUESTION 4 needs to be answered,

Required handwritten answer, Please be sure . Don't provide wrong answer. 1)An engine produces 238 hp at 5872 rpm. If the tractive force of the vehicle produces is 40 lbf, calculate the torque that the engine produces, in ft-lbf, when the vehicle is at constant speed.

I need answers to questions 1, 2, and 3 pertaining to the print provided. Note: A tutor keeps putting 1 question into 3 parts and wasted so many of my questions. Never had a issue before until now, please allow a different tutor to answer because I was told I am allowed 3 of these questions.

Moving to another question will save this response. Question 1 Which of the following statement is NOT correct? Fluid Mechanics is the study of the behaviour of fluids. Fluid Mechanics is the study of the behaviour of solids. Fluid Mechanics is the study of the behaviour of liquids. Fluid Mechanics is the study of the behaviour of gases.

Solve it Properly and with right answer.

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

I need these three parts answered, if you are unable to answer all three parts please leave it for another tutor to answer, thank you.

You are given a metal rod, cut to a length of 12 in plus/minus .25in. Then you need to cut off 2 in with an accuracy of plus/minus .25 tolerance. You end up with a 10 in rod but what is the tolerance? (hint: rely on the basic principle of tolerance
