Shaft Work in Compressible Flow Machines Solution

Follow our step by step solution on how to calculate Shaft Work in Compressible Flow Machines?

FIRST Step Consider the formula

W s = (h 1 + \frac{{C 1}^{2}}{2}) - (h 2 + \frac{{C 2}^{2}}{2})

Next Step Substitute values of Variables

∴

W s = (387.6KJ + \frac{{30.8m/s}^{2}}{2}) - (548.5KJ + \frac{{17m/s}^{2}}{2})

Next Step Convert Units

∴

W s = (387600J + \frac{{30.8m/s}^{2}}{2}) - (548500J + \frac{{17m/s}^{2}}{2})

Next Step Prepare to Evaluate

∴

W s = (387600 + \frac{{30.8}^{2}}{2}) - (548500 + \frac{17^{2}}{2})

Next Step Evaluate

∴

W s = -160570.18J

Next Step Convert to Output's Unit

∴

W s = -160.57018KJ

LAST Step Rounding Answer

∴

W s = -160.5702KJ
