President's Dining Room President's Dining Room The President's Dining Room is a dining room located in the northwest corner of the second floor of the White House. It is located directly above the Family Dining Room on the State Floor and looks out upon the North Lawn. The Dining Room is adjacent to the Family Kitchen, a small kitchen designed for use by the First Family, and served by a dumbwaiter connected to the main kitchen on the ground floor. The space was originally occupied by a bedroom suite known as the Prince of Wales Room. From 1929 to 1948, this suite was
Lift-to-drag ratio edged wings, and formula_3 the zero-lift drag coefficient. Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading. It can be shown that two main drivers of maximum lift-to-drag ratio for a fixed wing aircraft are wingspan and total wetted area. One method for estimating the zero-lift drag coefficient of an aircraft is the equivalent skin-friction method. For a well designed aircraft, zero-lift drag (or parasite drag) is mostly made up of skin friction drag plus a small percentage of pressure drag caused by flow separation. The
