Given a flow velocity of 7 meters per second and an inner diameter of 42 mm, determine the flow rate

Given a flow velocity of 7 meters per second and an inner diameter of 42 mm for the pipe, determine the flow rate; the density of LNG is 0.426. Please provide the calculation process. Thank you.
For your own safety, it is recommended that you stay away from chemicals~
The pipe cross-sectional area is calculated based on the pipe diameter; multiplying this by the flow velocity gives the volumetric flow rate, and multiplying that by the density yields the mass flow rate.
Qw=Qv*ρ=0.7854*3600*7*0.042*0.042*0.426=14.87 t/h
Qw=Qv*ρ=0.785*3600*7*0.042*0.042*0.426*1000=14865.46 kg/h
GB 51156-2015 Code for Design of Liquefied Natural Gas Reception Stations 5.1.10 The design flow velocity for liquefied natural gas pipelines should not exceed 7 m/s. A flow rate of 7 meters is acceptable; it’s not certain whether this represents the most economical flow rate
Simple, brutal, and straightforward~~~~
In this case, you should stay away from the chemical industry.
