Answer. The mathematical expression for work is dependent on a number of factors. In this case, to compress a gas at a constant temperature, work is the product of pressure times the change in the volume of the gas. W=PdV The states of the gas such as pressure and volume before and a...
35.6.3 Atomizing air pressure and volume Droplet size should be small, relative to the particle size of product to be coated. For example, coating of tablets may need less than 2 bar (30 psi) pressure. Higher pressure and air volume will result in a higher atomization air velocity, increas...
Instead of the "external pressure" Pext, the pressure Psys,mb on the piston or other moving boundary (hence the subscript mb), which is nearly equal to the system pressure Psys, should be used in the integral over volume. This formula only requires that Psys(V) and T are well ...
This formula calculates the efficiency of a person or a system in completing a certain amount of work within a specific time frame. The “Amount of work done” refers to the quantity or volume of work accomplished, while the “Time taken” represents the duration or time required to complete...

The work done on a gas at constant pressure can be calculated using the formula W = PΔV, where W is the work done, P is the pressure, and ΔV is the change in volume. This formula assumes that the pressure remains constant throughout the process and can be used for both expansion...
An ideal gas with pressure p1=2 bar and volume V1=3m3 is expanding under constant pressure to the volume V2=3V1. Then we compress the gas isothermally back to V1. Finally the gas cools down to initial pressure p1. Calculate the total amount of work. Homework Equations Work done is ...
With such high stakes, work stress should never be ignored.Ridiculous demands, bullying, perfectionism, and immense pressure from parents, peers, employers, and the individuals themselves all contribute to this vicious cycle. On top of that, an education system that focuses on conformity—and ...
This process, from reviewing the first page of medical records to code assignment, must be completed within 10 min, placing significant time pressure and accuracy demands on coders. Such intensive work with stringent time constraints tests coders’ professional competence and mental resilience. Further...
There is a long-standing need for a direct determination of solid-liquid work of adhesion due to its central role in several scientific and industrial fields. Here, a method is introduced to determine the value of adhesion work on flat surfaces directly,
