you look up the specific gravity of 96% H2SO4 and find it is 1.858.calculate the weight
Ethanol
(1) Describe the production of ethanol in Scottish Whisky beverages. Be sure to include a discussion on dangers of impurities
(2) Explain the impact of ethanol on the human body
(3) List th
At atmospheric pressure ethyl acetate and ethyl alcohol form an azeotropic mixture containing 53.9% mole of ethyl acetate and boiling at 71.8°C.
a) Estimate the values of A & B in the empirical van Laar equation
A heater (heat source temperature = 527 K) and turbine are connected in series as shown below:
Modeling eye movements is commonly performed in the Matlab/Simulink pacakage. Based on the Physiological evidence, oculomotor plants have been designed to simulate various eye movements. Choose two eye movement models, one for saccades and the other for pursuit, and simulate the following amplitudes
To determine the temperature that occurred in a ?re in a warehouse, the arson investigator noticed that the relief valve on a methane storage tank had popped open at 3000 psig, the rated value. Before the ?re started, the tank was presumably at ambient conditions and the gage read 1950 psig. If
A stream of propane is throttled from 4.298 bar and 450 K to 0.22 bar. This process is irreversible due to frictional losses at the nozzle.
a. In words or equations, why are frictional losses irreversible?
Calculate the adiabatic flame temperature of acetylenes gas at a pressure of 1 bar under the following conditions. The reactants are initially at 298K. Assume that the acetylene reacts completely to form CO_{2} and H_{2}O:
The Clausius-Clapeyron equation gives us an expression for dP/dT. Now we will derive an analog to the Clausius-Clapeyron equation by obtaining an expression for dT/dµ when two phases are at equilibrium. For simplicity, let’s derive this fo
A stream of steam at 15 bar and 300 ^{o}C is used to produce work using a steam turbine.
a. Before the turbine, steam flows in a pipe (4 cm in diameter) at a mass flow rate of 3 g/s. Calculate the mean velocity in the pipe
Calculate the pressure at the bottom of a column of Ethanol 100 ft high using a pressure (force) balance in American Engineering Units.
