Water (70°F) is draining from a tank through a galvanized iron pipe. The pipe length is...
Water flows from the upper tank to the lower tank through a cast iron pipe of total length L-1100 ft through one half-closed gate valve, four regular 90° flanged elbows, and entrance/exit as shown. For 2 cases with the same pipe perimeter P 12 in., compute the volume flow rate (ft /s) through: circular pipe of diameter D, and equilateral triangular pipe with each side a. a) b) Note that the flow areas and hydraulic diameters will be different. Find...
13) A tank of area Ao is draining in laminar flow through a pipe of diameter D and length L, as shown in Fig. P4.92. Neglecting the exit-jet kinetic energy and assuming the pipe flow is driven by the hydrostatic pressure at its entrance, derive a formula for the tank level h ) if its initial level is ho Area Ao V(t)
A water tank filled with solar-heated water at 40°C is to be used for showers in a field using gravity-driven flow. The system includes 39 m of 1.5-cm-diameter galvanized iron piping with four miter bends (90°) without vanes and a wide-open globe valve. If water is to flow at a rate of 1.2 L/S through the shower head, determine how high the water level in the tank must be from the exit level of the shower. Disregard the losses at...
1) Water at "standard" conditions flows from the tank through a 6" schedule 40 pipe of length Land drains into an open reservoir at a rate of 500 gal min1. The water in the tank is h 10 m above the open end of the pipe. With all other conditions the same, we replace the 6" pipe with an 8" pipe. What is the new flowrate, Q lgal min']? (assume entrance losses and kinetic energy are negligible.) - -0 Gven...
A farmer is to pump water at 70'F from a river to a water storage tank nearby using a 125-ft-long, 5-in-diameter plastic pipe with three flanged 90 smooth bends. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the river normal to the flow direction of water to take advantage of the dynamic pressure. The elevation difference between the river and the free surface of the tank is 12 ft. For a...

Water at 15-Celsius flowing through 25 meters of 100mm- diameter galvanized iron pipe, causes a head loss (due to pipe friction) of 75mm. Find the flow rate
Problem 1. Water flows from a large tank through a smooth pipe of length 80 m. Both the tank free surface and jet exit are exposed to the atmosphere. Take the density of water p = 1000 kg/m3, dynamic viscosity of water u = 0.001 kg/m.s, atmospheric pressure = 100 kPa, and gravity = 9.8 m/s2. Calculate the volumetric flow rate through the pipe. Neglect entrance losses to the pipe. Hint: Consider the inlet and outlet sections of the pipe...

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...
