Ammonia pipe diameter calculation
Thread Content
400 kilograms per hour of ammonia gas needs to be injected into the water stream. The pressure of the ammonia gas is 0.5–1.0 MPa, and its temperature is 40°C. What is the required diameter of the pipe for this ammonia gas? What would be the diameter of the pipe if liquid ammonia were used instead, with the same pressure and temperature?
When it is ammonia gas, the pipe diameter is DN80； When switched to liquid ammonia at the same temperature and pressure (ammonia water???), the DN20 pipe diameter ； It should be noted that at 40 degrees, the vapor pressure of ammonia reaches 1554 kPa, and it exists in a gaseous state at 0.5–1.0 MPa. At the same temperature and pressure, using ammonia water gives a similar result.
