| Açıklama | A. Objective: To investigate the validity of Bernoullis Theorem as applied to the flow of water in a tapering circular duct. B. Theory: Considering flow at two sections in a pipe, Bernoullis equation may be written as For this apparatus z1=z2 and p=r.g.h so, one can write is the Velocity head h1is the Static head. H is the Total Head and can be defined as Hence, if Bernoullis Theorem is obeyed, the Total Head is constant at all sections along the duct. C. Equipment: This experiment can be performed by using the service module and the Bernoulli apparatus in our laboratory a)Hydraulic Bench Service Module The Hydraulic Bench Service Module is shown in Figure 1. Parts of thc Bench arc numbered in this figure. Operation of the Hydraulic Bench is explained below; Figure 1 A self-priming centrifugal pump, 1N, draws water from sump tank, 1G, and delivers into a vertical transparent pipe, 1M. A panel mounted control valve, 1 C, is used to regulate the flow in the pipe which terminates in a quick release pipe connector, 1o, allows for rapid substitution of accessories which are supplied with a flexible supply tube terminating a mating connector. Special purpose terminations may be connected to the pump supply by unscrewing connector, 1o. Water discharging from the accessory on test is collected in a volumetric measuring tank, 1 U. This tank is stepped to accommodate low or high flow rates and incorporates a stilling baffle, 1 S, to reduce turbulence. A remote sight tube and scale, 1 A, ia connected to a tapping, 1T, in the base of the volumetric tank and gives an instantaneous indication of water level. A dump valve, 1V, in the base of the volumetric tank is operated by a remote actuator, 1E. Lifting the actuator opens the dump valve allowing the entrained water to return to the sump, 1G, for recycling. When lifted, a twist of 90° at the actuator will retain the b) Bernoullis Theorem Demonstration Apparatus Bernoullis Theorem Dem... |
