Figure 1.6 – CENTRIFUGAL BLOWER Dryers use centrifugal blower, where air is radially discharged from the impeller, (or fan wheel), so turns 90° from its inlet to its outlet (Figure 1.6). Air enters the impeller at the blade inlet with an absolute velocity of v_1. As the fluid elements flow through the blade passage, they accelerate. Moreover, a guiding pressure is exerted on the fluid elements by the blades because of the rotation of the impeller.…

manipulator arm The significance of making dynamic analysis for the manipulator is to determine accurately the torques that are required to carry a specific amount of load on the end effector at a particular position with a predetermined acceleration and velocity. The dynamic analysis is mainly used to determine the maximum torque needed during the mission; in order to select the DC-servomotors needed for each joint. Usually in case of complex manipulator it is suitable to use Lagrangian…

frames of reference. On the whole, in the film Frames of Reference, the educationists not only discuss the distinctions between noninertial and inertial frames of reference but also expound on other crucial physics concepts such as the addition of velocities, the three dimensions of view, as well as the projectile, relative,…

=2[(∂u/∂x)^2+(∂v/∂y)^2+(∂w/∂z)^2 ]+(∂v/∂x+∂u/∂y)^2+(∂w/∂y+∂v/∂z)^2+(∂u/∂z+∂w/∂x)^2 is the dissipation function which represents the time rate at which energy is being dissipated per unit volume through the action of viscosity. Here, u,v and w are the velocity components of the fluid along thex,y and z directions respectively.C_P is the specific heat at constant pressure, T is the temperature, K is the thermal conductivity and γ is the Casson fluid parameter. Species Concentration equation…

However, taking the radial velocity to be a maximum (81.082 km s-1), an expected Doppler Shift would be z = 2.7e-4 depending on the relative movement of the star. For the line He II  4686 A, the expected shift would be 1.27 A, which means that He II  4686 A would be observed…

Forensic chemistry is the application of chemistry to provide information for use in courts of law or in public discussion and debate. It is a special branch of chemistry that is concerned with identifying the substances present in samples. A forensic chemist analyses predominantly biological samples such as blood, saliva, and semen (of which all contain DNA, proteins and amino acids) that are brought in from the crime scenes and reaches a conclusion based on tests run on that piece of evidence.…

in terms of ε =ka, is expected to converge as more and more terms are considered in the expansion. Convergence does not occur for steep waves unless a different perturbation parameter from that of Stokes is chosen. The perturbation expansion for velocity potential Φ can be written as below; Φ= ε Φ_1+ ε^2 Φ_2+⋯⋯ in which ε=ka is the perturbation expansion parameter. In this expansion, Φ_1 is the first order theory (linear theory), Φ_2 is the second order theory and so on. The Stokes expansion…

The variation of poisson’s ratio (σ), depends on the variation of the values and relative values of (E) and (G) in Equation (10) and (Ul) and (Us) in Equation (11). For any material (E) and (G) as well as (Ul) and (Us) tends to increase or decrease together. Therefore, we cannot decide the variation of (σ) in the same or opposite direction to that of (E) and (G). Using Equations 10 and 11 we can predict the behavior of (σ) according to which of the two elastic constants varies more than the…

1. Effect of obstructing hydraulic structures on the fish fauna: Dams, barrages, weirs or navigation locks built on a river for various purposes act as obstruction to the migration of the fishes. Various effects of such hydraulic structures are as follows: a) Barrier to the movement of fish to their spawning grounds. Several fish species require special regions to spawn. These hydraulic structures obstruct the movement of such species to their upstream spawning grounds where they reproduce. As…

In the aftermath of World War II, the U.S. Military was desperately in search of a serviceman rifle that could put rounds on target at extreme distances, just as the M1 Garand did during the war. In 1958, Eugene Stoner, the head engineer at the small arms engineering company- ArmaLite, came up with the company’s fifteenth rifle project: the AR-15. (Ar15.com, 2014) Soon after the rifle’s birth, the U.S. Military adopted the AR-15 in a fully automatic version known as the M16. The M16 allowed…
