The nth triangle number is the number of dots composing a triangle with n dots on a side, and is equal to the sum of the n natural numbers from 1 to n. . Thus, Packing efficiency = 2 ( π r 2) 8 r 2. It is very important to add only the heats that are supplied(I am specifically using plural form to emphasise on this fact) and not the net heat exchange for the process. The flux balance equations are obtained by a Galerkin finite-element-type formulation. Efficiency is doing things the right way in the best possible manner with the least resources, time and effort. As a result of this statement, we define the thermal efficiency, η th, of any heat engine as the ratio of the work it does, W, to the heat input at the high temperature, Q H..

Various elements that determine the efficiency of a steam turbine include: thermodynamic (temperature and steam pressure) and hydraulic (inlet fluid . Calculating the output power of an EPS, which is dc, is simply the output voltage multiplied by the output current: Equation 2: Output Power. Thus, +! I. We have also seen that in an AC circuit, the quantity cos (Φ) is . Degree of Reaction 5. Conceptually, as the list begins, efficiency increases and the team's performance rises (on the upslope of the triangle, y-axis) as work is done and time is utilized (along the x-axis). Total area of oven sides (less heater modules) = 295m 2. Inductive L I lags V S by 90°. Total area of heater modules = 105m 2. Introduction to Axial Flow Compressor 2. Dimensions and Importance of Dimensions and Units. Since the fin efficiency is inversely proportional to Λ, it can be improved either by increasing k and B, or by decreasing 〈h〉 and L. If the average heat transfer coefficient, 〈h〉, is increased due to an increase in the air velocity past the fin, the fin efficiency decreases.This means that the length of the fin, L, can be smaller for the larger 〈h〉 if the fin efficiency remains . Such fans are used generally for 94. Velocity triangle in Francis turbine (Reference: Wikipedia.com) Induction motors: pf = 0.8 triangle: θ = arccos(0.8) = 36.86 degrees Pa = 500/0.8 = 625 VA Pr = sqrt(625^2-500^2) = 375 VAR Synchronous motors: pf = 0.707 triangle: θ = arccos(0.707) = 45 degrees Pa = 500/0.707 = 707 VA Pr = sqrt(707^2-500^2) = 499.85 VAR I am uncertain of how I can.

For example if we give 10J energy to a machine and it's generating 9J worth output, so efficiency of the machine will be (output/input) = 9/10 = 0.9 (no unit). Once an oxygen requirement (SOR, lbs/day) and efficiency (SOTE, %) have been determined an air rate (scfm) can be calculated using the following formula: Unit Conversion Factor 25.056 = 0.075 x 0.232 x 1440 These are the conventions used in this book. For maximum efficiency. Performance. Thus, to calculate the packing efficiency divide equation (5) by equation (4). b = √2 a . Fig. When work is done on an object, energy is transferred. The power factor is the cosine angle between the voltage and current. As these three elements are represented by a "right-angled triangle", their relationship can be defined as: S 2 = P 2 + Q 2, where: P is the real power in watts (W), Q is the reactive power in volt-amperes reactive (VAr) and S is the apparent power in volt-amperes (VA).

Thus, output KVA corresponding to maximum efficiency. It is a simple philosophy, and for those familiar with Stephen Covey's work could be referred to as "our lighthouse". Efficiency focuses on process. Function eta_fin_straight_triangular_ND returns the fin efficiency of a triangular fin with a rectangular base given the product of the fin parameter, m, and fin length, L, where m is defined as: Fin Efficiency Index It has no unit and expressed in percentage. Efficiency is easily measurable by analysing specific metrics. If we further reduce the value of ϕ (below 200), it increases the efficiency but also results in long size of blades and increased friction losses. The efficiency formula is applied to calculate the efficiency of any given input. The laminar flow efficiency equation, ri = wA/Q, [for t] < 1] (2) leads to the Deutsch equation when it is assumed that the particles are uniformly distributed over the section by tur- The Triangle Formula are given below as, Perimeter of a triangle = a + b + c Area of a triangle = 1 2bh A r e a o f a t r i a n g l e = 1 2 b h Where, b is the base of the triangle.

S. Environmental Protection Agency Research Triangle Park, NC 27711 January 9, 1995 One way of writing the equation for efficiency is: Efficiency = (Output power) / (Output power + losses) For a transformer running at full rated VA, the losses will be constant no matter what the load power factor. That is the Excel Function Warning I am talking about. Calculating efficiency worksheet with answers. The goal was to show that by designing and building a kitchen with efficiency in mind, overall construction costs could be reduced. A centrifugal Pump impeller has an external diameter of 12 inches and a discharge area of 1.2ft. During one particular week, the two cars went a combined total of 1125 miles, for a total gas consumption of 55 gallons. Efficiency (η) is the ratio of output power to input power: Equation 1: Efficiency. Motor Efficiency Improvement EPACT was passed in 1992 but motor efficiency provisions took effect in 1997. From equation (6) we can see that, the lower is the friction mean effective pressure (FMEP), the higher is the mechanical efficiency of the internal combustion engine. The steam turbine efficiency can be defined as the ratio of the turbine useful output energy to the energy to which it is delivered. Efficiency is asking "What needs to be done". So the more powerful a device is, the more energy it will transfer each second . Commercial, institutional and, particularly, industrial operations use substantial amounts of power for electric motors. Then, based on the technique of minimizing the loss function of the neural network, the proposed numerical methods reduce the fractional . the calculated efficiency, such as "sneakage."4 An approach that appears to work quite well is presented here—the Hazen short-circuiting formula. For determining the packing efficiency, we consider a cube with the length of the edge, a face diagonal of length b and diagonal of cube represented as c. In the triangle EFD, apply according to the theorem of Pythagoras, b2 = a2 + a2.
