If the volumetric flowrate of air (Q)is large enough, the pressure within the constriction will be low enough to draw the water upinto the tube. Determine the volumetric flow rate (Q) in m³/s at section (1) to draw the waterinto section (2). Neglect compressibility and viscous effects.Here the density of air 1 kg/m³ and the density of water is 1000 kg/m³. Also, the gravitationalacceleration (g) is approximated at 10 m/s². The cross-section area at section (1) is A₁ = 0.002m², and the cross-section area (2), A2 is four time smaller than A₁, thus A₁ = 4A,. The heightof water column (h) is 0.3 m.

If the friction loss in the system is 5.10 N.m/N find (a) the power delivered to the turbine by the fluid and (b) If the mechanical efficiency of the turbine is 80 % find the power output from the turbine.
A liquid (SG = 0.920) is being pumped from a reservoir as shown. The pressures at points 1 and 2 are -8 psi and 44 psi, respectively. The rate of flow in the pipe is 0.714 ft3/s. Neglect energy (friction) losses in the system. Use x = 4 ft., y = 7 ft. Use 1 hp = 550 lb-ft/s. Efficiency of the pump is 91%. What is the output power of the pump, in hp?

4. Water flows steadily from a reservoir tank through a pipe system having various sizes and elevations. Viscous effects can be ignored, and no external force is applied to the system. It is useful to normalize pressure and velocity in such a way that they have a dimension of length, namely 2 and 22, often called pressure head and velocity head, respectively. At points A-G marked in the figure below, evaluate pressure head and velocity head. Also evaluate elevation head (thus, elevation itself) and total head (sum of all three heads). Are total heads at points A-G remain constant? Why or why not? For pressure head, use gauge pressure. For elevation head, use G as a reference elevation (that is, z = 0). 15 ft 6 ft D Flow 6-in Schedule 40 pipe 21 ft 2-in Schedule 40 pipe 1.25-in diameter G
