![]() So you actually get 1,882 foot pounds, Oops. So I need to divide by 12 to convert these inches in the inch pounds two ft in foot pounds. But I need to check units these are inch pounds, which are not units of work, units of work again, our foot pounds. So now you're just plugging in and what you get is 22,588. So using just my normal immigration rules, I'm going to plug in and I will get let's see here, V. ![]() And the only thing that's left Is the to the -1.4 DV. Which means that we have 100,953 that's gonna come out. How to Calculate the Energy of steam if it is having temperature higher than its boiling point, Specific Enthalpy of Super Heated Steam can be calculated from the regular equation, hs hg + Cp ( Ts - Tf ) Cp - Specific Heat of Steam at Constant Pressure, which can be considered as 1.860 KJ/Kg.C, Ts - Temperature of super heated Steam, T f. Okay, so uh I can plug into my integral which is the work is the integral from the initial volume to the final volume of P as a function of V. No matter how pressure and volume change, this will always be true. Okay, So that tells me and I know that that is always p times feed to the 1.4. And I know that my initial volume is a 100 And she's cute to the 1.4. Option available to use either mass flow or power output as input. The calculator can calculate turbine isentropic efficiency if the steam inlet and outlet conditions or calculate outlet conditions for known values of isentropic efficiency. And then I can turn P into a function of the, so I know that my initially Pressure is £160 print squared. Calculate steam turbine performance estimates. So what I can do is I can plug in here based on my initial values and I can find what K. So um first I need P to be a function of V. Okay, so we're working with inch pounds right now basically. Now it is extremely important that we notice we are in inches but work is in units of foot pounds, not inch pounds foot pounds. Thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, a steam turbine or a steam engine, Efficiency of transmission is the ratio of output of transmission to input of transmission & Propulsive efficiency is the efficiency with which the energy contained in a fuel. And I know that V one equals 100 cubic inches And I know that V two or final volume is 800in cute. Uh I know that the initial pressure P one is 100 and 60 uh huh, pounds per square inch. I know that work is the integral from the first volume to the second volume of P as a function of the devi right. That's always going to be the same number. Step 2: Write down the work formula for change in velocity and place the values in it.We know a couple simple things. W = 10,000 J Example: Work with velocity changeįind the total work done, if the initial velocity of an object is 10 m/s, final velocity is 50 m/s, and mass is 20 kg. Step 2: Use the work done formula and place the values. ![]() Example: Work with force and displacementįind the work done by a car if the force applied on the car is 20 N with a displacement of 500 m. S.I unit of work is Joule J or Newton-meter Nm.Ĭalculating work is absolutely simple, either you use work done calculator or above-mentioned formula for the calculation. In other words, it is generally represented as the product of force and displacement. Work is the energy transferred to or from an object by applying the force along with displacement. Here is the formula to calculate work from change in velocity. The work done formula can be expressed as:ĭ = Distance Work with change in velocity Work formula is generally used in physics to find the work done by an object. Work formulaĪre you looking for work physics formula? In this space, we will explain definition of total work, how to find work for physics problems, work equation for physics, and few examples to calculate work. It requires mass, initial velocity, and final velocity of the object to get the total work done. Total work done can be calculated with ease using this online work calculator for physics.
