Using the vapor pressure data provided below, estimatei) the heat of sublimation of ice,ii) the heat of vaporization of water,iii) the heat of fusion of ice and compare your estimate with the published value of 6010 J/moLiv) the triple point of wate
A heater (heat source temperature = 527 K) and turbine are connected in series as shown below:
how to calculate amount of ammonia adsorbed per kg of adsobent in ammonia calcium chloride adsorption process?
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:
You are asked to make up a laboratory solution of 0.10 molar H2SO4 from concentrated (96%) H_{2}SO_{4} at 56°F. The barometric pressure reads 750 mmHg. You look up the specific gravity of 96% H_{2}SO_{4} and find it is listed at 1.858. Calculate:
(a) th
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
The feed to an ammonia synthesis reactor contain 25 mole% nitrogen and the balance hydrogen. The flow rate of the stream is 3000 kg/hr. Calculate the rate of flow of nitrogen into the reactor in kg/hr. (Hint: First calculate the average molecular weight of the mixture).
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?
