hi every one i appreciate help as ineed answer as soon a jetplane discharges a jet at rate of 28kg/s with a velocity of 950 m/s relative to the plane if the forward speed of the plane is 875km/h what is the thrust developped on the plane and the power developed at the jet
the plane witch has now a weight of 2 mn now makes a climb of 3degrees to the horizontal and accerlates 0.15ms square
the thrust changes to 490 kn find the lift to drag ratio
3- on completion of the climb the aircraft makes a level turn of radius 1.5km at a speed of 850 km/h find the correct angle of bank and the total lift when turning
To find the thrust developed on the plane and the power developed by the jet, you need to use some basic physics equations.
1. Thrust developed on the plane:
Thrust is calculated by multiplying the mass flow rate of the jet with the change in velocity of the jet relative to the plane. In this case, the mass flow rate is given as 28 kg/s and the velocity of the jet relative to the plane is 950 m/s. We can calculate the thrust as follows:
Thrust = mass flow rate * change in velocity
Thrust = 28 kg/s * 950 m/s
Thrust = 26,600 N
2. Power developed by the jet:
Power is calculated by multiplying the thrust with the forward speed of the plane. The forward speed of the plane is given as 875 km/h. However, we need to convert it to m/s for consistent units.
1 km/h = 0.277778 m/s
875 km/h = 875 * 0.277778 m/s = 243.05695 m/s
We can now calculate the power as follows:
Power = Thrust * forward speed of the plane
Power = 26,600 N * 243.05695 m/s
Power = 6,468,540 W or 6.47 MW
Next, let's move on to the second part of your question.
3. Lift-to-drag ratio:
To find the lift-to-drag ratio, we need to know the lift force and the drag force. Unfortunately, the information you provided does not include the lift force. Without that, it is not possible to calculate the lift-to-drag ratio accurately.
Finally, let's address the last part of your question.
4. Angle of bank and total lift when turning:
To find the correct angle of bank and the total lift when turning, we need the radius of the turn, the speed of the turn, and some additional information like the mass or weight of the plane, the lift coefficient, and the angle of attack. Without this additional information, we cannot accurately determine the angle of bank and the total lift when turning.
In summary, we were able to calculate the thrust developed on the plane and the power developed by the jet. However, we do not have enough information to calculate the lift-to-drag ratio, angle of bank, or total lift when turning. It is important to provide all relevant details for a complete analysis.
