Dear all
Although API 521 suggests that a nominal diameter of (DN) 20 × DN 25(NPS 3/4 × NPS 1) relief valve is commonly used for only thermal relieve scenarios because oversizing in this case is fine, I would like to calculate the 'exact' relieving flow and DP's for a thermal expansion PSV in...
Dear
I would like to calculate how much meters of pipeline it takes to cool down HCl from -60°C to -30 °C in a pipeline using only air flow around it.
The flow of HCl through the pipeline is 30000 kg/u.
I took 3 m/s of wind at 20 °C.
The pipeline is made of uninsulated stainless steel and is...
