Concept explainers

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Textbook Question

Chapter 11, Problem 11.29P

Tests by the Byron Jackson Co. of a 14.62-in-diameter centrifugal water pump at 2134 r/min yield the following data:

G, ft’/s	0	2	4	6	8	10
H, ft	340	340	340	330	300	220
bhp	135	160	205	255	330	330

What is the BEP? What is the specific speed? Estimate the maximum discharge possible.

Pl 1.29 If the scaling laws are applied to the pump of Prob. Pl 1.28 for the same impeller diameter, determine (a) the speed for which the shutoff head will be 280 ft, (/?) the speed for which the BEP flow rate will be 8.0 ft³/s, and (c) the speed for which the BEP conditions will require 80 hp.

An aqueduct is required to supply water to the community.Data: Families = 12 Average members per family = 3 people Breakfast, lunch and dinner = 15 total liters / family Showers = 10lt / person, one daily shower Kitchen wash = 13lts / day Total distance of the pipeline to the storage tank = 1200 meters Total height H from the pump point to delivery to the tank = 70 meters Determine: Estimation of the total volume of the recommended tank, an autonomy of at leas 2 days of storage. It is required to propose a pump that allows at least filling the tank between 5 to 12 hours operation, it must include details of the pump, as well as its curve Image: schematic detail of the proposed system

The dimensions of a Francis radial-flow hydroturbine are r2 = 2.00 m, r1 = 1.30 m, b2 = 0.85 m, and b1 = 2.10 m, where location 2 is the inlet and location 1 is the outlet. At the turbine inlet and outflow, the runner blade angles are β2 = 71.4° and β1 = 15.3°, respectively. The runner rotates at a rate of ń = 160 rpm. At design conditions, the volume flow rate is 80.0 m3 /s. (a) State the necessary assumptions and calculate the angle α2 at which the wicket gates should turn the flow (Figure Q1), with α2 measured from the radial direction at the runner inlet. (b) Calculate the swirl angle α1 (Figure Q1), where α1 is the angle measured from the radial direction at the runner output. (c) Calculate the needed net head and power output. (d) Discuss the actual power output and head required for actual case of the turbine (irreversibility not neglected). (Properties For water at 20oC, ρ = 998.0 kg/m3)
