pressure drag coefficient meaning in Hindi

Examples

1. where U _ { \ textrm { wind } } is the far-field wind speed; C _ { \ textrm { p1 } } is a local pressure drag coefficient for the building, defined at the location of the upstream opening; C _ { \ textrm { p2 } } is a local pressure drag coefficient for the building, defined at the location of the downstream opening; A _ { \ textrm { 1 } } is the cross-sectional area of the upstream opening; A _ { \ textrm { 2 } } is the cross-sectional area of the downstream opening; C _ { \ textrm { 1 } } is the discharge coefficient of the upstream opening; and C _ { \ textrm { 2 } } is the discharge coefficient of the downstream opening.
