Both nozzle jets in Fig. P6.9 discharge horizontally into the atmosphere with a velocity of 40 fps. The liquid has a specific weight of 62.4 lbift. The axes of the pipe and both nozzles all lie in a horizontal plane. Find the magnitude and direction of the resultant force on this double nozzle while neglecting friction. 20 6-in-dia

If anyone can help with this problem I would appreciate it. Thank you! Answers listed in the book are: a) 5, (b) 4.4 m/s, (c) −ρV 22 H2w((1 + cos θ)i + sin θj), (d) magnitude ×1/4

A model rocket has engine with an average thrust of 2.82 N. The rocket mass is 71.5 g, which includes fuel mass 27.3 g. The duration of fuel burning is 2.52 s. What is the final speed vf of this rocket if it were to be fired from International Space Station with initial speed vi=7660 m/s? Assume the fuel burns at a constant rate.

An ideal water jet with volume flow rate of 0.05 m^ 3 / s strikes a flat plate placed normal to its path and exerts a force 1000 N Considering the density of water as 1000 kg / (m ^ 3) , find the diameter (in mm) of the water jet.
