Problem 14.2 A jet of water (r = 1000 kg/m³) is deflected by a vane mounted on a cart. The water jet has a constant cross-sectional area, A = 50 cm², which is projected off the vane at an angle q = 30° with respect to the horizontal. The pressure everywhere within the jet is atmospheric. The incoming jet velocity (with respect to the ground) is Vjet = 4.5 m/s. The cart has mass 50kg. Determine: a. the forces, Fx and Fy required to hold the cart stationary Vjet Vcart Fy Fx b. the horizontal force component, Fx, if the cart moves to the right at the constant velocity, Vcart = 3 m/s c. the horizontal acceleration of the cart at the instant when the cart moves with velocity Vcart = 2.5 m/s if no horizontal forces are applied Ans: a) 10 N
3. A pipe with varying cross-sectional areas is set up vertically as shown in the drawing. Water enters the pipe from the top wider end at a speed of 300 cm/s. Calculate (a) the mass flow rate of water (the amount of mass entering/exiting the piper every second) and (b) the water pressure at the bottom narrower end section of the piper.

3. Air is flowing down a circular duct as shown in the figure. At station 1 the velocity is V₁ and the duct diameter is D₁. The duct gradually enlarges to station 2, where the air exits to the atmosphere, and the diameter is D₂. A conical centerbody with a cone angle of 30° is inserted into the duct exit. The diameter of the cone base is d. You may assume that the velocity is low enough that p = constant. control surface V₂ 1 0 = 30° V₂ F Figure for problem 3. (a) Find an expression for the gauge pressure at station 1 in terms of V₁, D₁, D₂, d, e, and p. What assumptions do you have to make to solve this problem? (b) What is the force, F, required to hold the cone in place? You may ignore the weight of the cone. Use the following values: V₁ = 20 m/s, D₁ = 30 cm, D₂ = 60 cm, and d = 58 cm. You may assume that the air density is at standard conditions, p = 1.225 kg/m².
Question Water enters the horizontal circular nozzle with the inlet diameter of 5 in. At the inlet section, fluid has uniformly distributed velocity of 20 ft/s and pressure of 85 psi. The water exits from the nozzle into the atmosphere at the outlet section where the uniformly distributed velocity is 100 ft/s. Determine the axial component of the anchoring force required to hold the contraction in place. Answer The axial component of the anchoring force required to hold the contraction in place is lbf.
PROBLEM 2 Consider a firefighter who is standing on a ladder and spraying water with a hose into Chief Inspector Jacques Clouseau's (Figure 3a) third-story apartment. A diagram of the hose/nozzle used by the firefighter is shown in Figure 3b. Assume the nozzle has little effect on the flow in the hose and water in the hose/nozzle is incompressible. The temperature of the water in the hose is 15 °C.

3. A pump steadily circulates oil used for lubricating heavy machine tools. The volume flow rate and temperature of the oil are 300 gal/min and 104°F, respectively. At 104°F, the kinematic viscosity and the specific gravity of the oil are 2.15 x 10-3 ft² /s and 0.89, respectively. The pipe lengths are 25 ft for the 4-in diameter pipe and 75 ft for the 3-in diameter one. The Schedule-40 steel pipe has an average roughness element size of 0.0018 in. If all minor losses can be ignored, evaluate how much power (in a unit of horsepower) the pump delivers to the oil. 6 ft 22 ft Flow 15 ft Discharge line 3-in Schedule 40 Suction line 4-in Schedule 40 steel pipe steel pipe Pump
Water flows into the pipe connection shown at '6' and '2' and leaves the system at '1'. It is not open to the atmosphere at any connection. The gauge pressure at both inlets is 12 psig and the velocity at both inlets is 9.5 ft/sec. Determine the horizontal force (lbf) needed to hold the fittings in place. 2 7.5" 1 2.5" 3 4 5 6 1.0"
