A solid rocket motor has a chamber diameter d = 12 cm and a nozzle exit diameter d = 9 cm. The density of the propellant is p, = 1,750 kg / m² and the average regression rate in the combustion chamber is V, = 1.2 cm/s (it burns over the entire cross-sectional area of the combustion chamber a linear 1.2 cm/s of propellant, imagine the red line below moving 1.2 cm per second and how much propellant with that pass over in that time). The exhaust gases have a pressure of p. = 11 kPa, a temperature of T, = 1,975°C, and a gas constant R-400- Find the velocity at the exit of the kg-K nozzle.

Dynamics of Rigid Bodies Problem: 1.) A diver jumps from a height of 3.0 metres above the height of the water and touches the surface 1.0 s later. What was his velocity when he hit the water? 2.) A motorcyclist, travelling at a speed of 30 m/s, sees an obstacle 100 metres in front of him and puts on the brakes. He hits it 5.0 seconds later. If the motorcycle slows down uniformly, how fast was it going at the instant of the collision?
For a venturi meter given below, the volumetric flow rate is defined in terms of the geometrical parameters, the density of working fluid (p), and density of the manometer liquid (pm) as 4.

The thrust F of a Free propeller, either aircraft of marine, depends upon density ρ, the rotation rate n in r/s, the diameter D, and the forward velocity V. Viscous effects are slight and neglected here. Tests of a 25-cm-diameter model aircraft propeller, in a sea-level wind tunnel, yield the following thrust data at a velocity of 20 m/s : Rotation Rate, r/min____4800____6000____8000 Measured thrust, N____6.1____19____47 Use the dimensionless data to predict the thrust, in Newtons, of a similar 1.6-m-diameter prototype propeller when rotating at 3800 r/min and flying at 225 mi/h at 4000-m standard altitude.
