You are responsible for the purchase of oxygen gas which, before use, will be stored at a pressure of 200 atm at 300 k in a cylindrical vessel of diameter 0.2 m and height 2 m. would you prefer that the gas behaved ideally or as a van der waals fluid? the van der waals constants for oxygen are a = 1.36 liters2 · atm· mole– 2 and b = 0.0318 liters/mole.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
