Determine the mass flow rate of fuel from the gasoline tank to the car's fuel injection system. Assume that the gasoline consumption of the car is 20 mpg when the car is moving at 60 mph. Use the specific gravity value of 0.72 for the gasoline.

Answers- a) V1= 19.9 ft/ s; V2 = 79.7 ft/ s; m = 103.4 lbm/s b)F=288 lbf

1) Water is pumped from a storage tank through a tube of 3.0 cm inside diameter at the rate of 0.001 m³/s. What is the kinetic energy per kg water in the tube?

A nozzle is attached to the end of a 3-in. diameter water pipe. A jet of water with a diameterof 1.5-in. discharges into the open atmosphere. The pressure in the pipe is P1 = 60 psig andthe rate of discharge of 60oF water at steady-state is Q = 400 gal/min. Calculate themagnitude and direction of the force necessary to hold the nozzle to the pipe.
