I need to write a function that takes an input string and returns it minus all vowels and another that returns it with each vowel duplicated. ie - in the first case, removeVowels("Zippy") would return "Zppy" and in the second case duplicateVowels("Zippy") would return "Ziippy". I know it is...
I'm still confused as to how to proceed. I think you are confusing the Clausius statement of the second law (which essentially says that the spontaneous transfer of heat does not occur from a cold reservoir to a hot reservoir) with the Kelvin-Planck statement (which says that it is not possible...
a firebox is at 750K and the ambient temp is 300K. The efficiency of a Carnot engine doing 150J of work as it transports energy between these constant temperature baths is 60%. The Carnot engine must take in energy 150/.60=250J from the hot reservoir and must put out 100J of energy by heat...
argon enters a turbine at a rate of 800 kg/min, a temp of 800C and a pressure of 1.5MPa. It expands adiabatically as it pushes on the turbine blades and exits at a pressure 300KPa. Calculate its temperature at exit.
The equations I am working with are PV^(gamma)=constant and...
A tank having a volume of .1 m^3 contains helium gas at 150 atm. How many balloons can the tank blow up if each filled balloon is a sphere .3 m in diameter at an absolute pressure of 1.2 atm.
Here is what I have so far: Assuming no gas gas escapes to the atmosphere during transfer, n is...
A tank having a volume of .100 m^3 contains helium gas at 150 atm. How many ballons can the tank blow up if each filled balloon is a sphere of .300 m in diameter at an absolute pressure of 1.2 atm?
Here is what I have so far: Assuming no gas is lost to the atmosphere, n is constant. R is...
