A gas tank (volume V (M = 28 kg/kml, viscosity u = 1.1-10–4Pa-s) initially at pressure po = 30 - 10°Pa and temperature T = 200 K and connected through a long pipe (L = 1500 m, dia- meter d = 0.2 m) to a reactor operating at atmospheric 40 m) contains ethylene pressure. 1. calculate the flow rate fed to the reactor when the valve placed at the pipe inlet is opened (assume isothermal transformations and f = 0.003); 2. calculate the time needed to halve the pressure in the tank; 3. determine the mass of gas discharged from the tank up to that time. which allow to dispose the condensate by gravity at the bottom of the stack.

Question
Transcribed Image Text:A gas tank (volume V = 40 m³) contains ethylene
(M = 28 kg/kmol, viscosity u = 1.1-10-4Pa-s) initially
at pressure po = 30 - 105Pa and temperature T = 200 K
and connected through a long pipe (L = 1500 m, dia-
meter d = 0.2 m) to a reactor operating at atmospheric
pressure.
1. calculate the flow rate fed to the reactor when the
valve placed at the pipe inlet is opened (assume
isothermal transformations and f = 0.003);
2. calculate the time needed to halve the pressure in
the tank;
3. determine the mass of gas discharged from the tank
up to that time.
which allow to dispose the condensate by gravity at the
bottom of the stack.
