R1 R2 Tank V‚ P P1 P2 F1 F2 Fig. 1 A Pressure system with two resistances Consider a pressure system with tank of volume V and varying pressure P at constant temperature. F1 is inlet flow through resistance R1 with source pressure P1. F2 is output flow through resistance R2 and flowing out at pressure P2. As the flows into and out of the tank are both influenced by the tank pressure‚ both flow resistances affect the time constant. A typical control problem would be to

Computational Fluid Dynamics (CFD) is the present day state-of-art technique for fluid flow analysis. Numerical simulation of 200 m3/hr capacity centrifugal pump carried out using commercial CFD package FLUENT is presented. The steady state simulations were carried out

Mrs.Mallard is the protagonist of this story and as well as a dynamic character who is changing rapidly. Mrs. Mallard actually changes twice throughout the course of this story. The first time she is told about her husband’s “death” by her sister Josephine. Mrs. Mallard immediately started to weep when she is told the

whether or not the author accomplished his goal‚ I am hard-pressed to make that determination‚ mainly due to my lack of experience in the procedure. However‚ I did find the explanation of the openness model convincing and somewhat refreshing to me. Dynamic omniscience‚ however‚ is a concept that may pose some challenges for many people; nevertheless‚ it is intellectually conceivable. Even though the “openness” label is new

these differential equations follow: so an increase in prey population later shows as an increase in predators and vice versa. But this is a general model and more insight into prey predator dynamics have been observed like an article by Helen.J.Edwards and co authors who studied prey population dynamics for these type of interactions:1)Prey may compete for resources in a single habitat‚ or may be segregated‚ thus competing only indirectly . 2)Models in which a single prey species moves between

A group can be defined as two or more humans that interact with one another‚ accept expectations and obligations as members of the group‚ and share a common identity. A definition of the term group should strike a balance between being sufficiently broad to include most social aggregates that are true groups and being sufficiently narrow to exclude most social aggregates that are not true groups. The following formal definition meets these criteria: A group is (a) two or more individuals (b)

Unknown to many‚ Dr. Jose Rizal celebrated his 25th birthday with a Lutheran minister‚ Karl Ulmer‚ and his family on June 19‚ 1886‚ in Wilhelmsfeld‚ an idyllic and quaint suburban district 15 miles from Heidelberg town. In commemoration of that occasion‚ the Ulmer family honored the “young Filipino eye doctor with a party in their house where strawberry punch was served‚” as recounted by Fritz‚ one of Pastor Ulmer’s sons. The Germans have a deep attachment and devotion to Rizal‚ and today he is
