Suppose you pour a gallon of water on a yowling cat 10 ft below your bedroom window.
(a) How much potential energy (ft · 1bf) does the water lose?
(b) How fast is the water traveling (ft/s) just before impact?
(c) True or false: Energy must be conserved therefore the kinetic energy of the water before impact must equal the kinetic energy of the cat after impact.
A fresh feed stream containing 4.0 mol% inert gas and a stoichiometric ratio of hydrogen and nitrogen is combined with a recycle stream and is fed to a system to produce ammonia according to the reaction: N2 + 3H2 = 2NH3
Solid NH4NO3 (ammonium nitrate) decomposes on heating to 400°C, forming N2O gas and water vapor, H2O. (a)Write a balanced chemical equation
Under these conditions, name one crystalline defect that you would expect to form in order to maintain charge neutrality. How many Cu+ ions are required for the creation of each defect? How would you express the chemical formula for this nonstoichiom..
Use Laplace transformation to solve the initial value problem
Water (1.25 kg/s) is to be heated from a pipeline temperature of 15°C to 85°C using superheated steam (13.75 kg/s) at 550°C and 3 MPa in a steady-state process to produce 15 kg/s of heated water. The heating is to be done in a mixing tank by directly..
describe the principles of a vapour adsorption refrigeration system and compare this to a vapour recompression system.
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
