Drag equation by experiment. Of particular importance is the formula_8 dependence on flow velocity, meaning that fluid drag increases with the square of flow velocity. When flow velocity is doubled, for example, not only does the fluid strike with twice the flow velocity, but twice the mass of fluid strikes per second. Therefore, the change of momentum per second is multiplied by four. Force is equivalent to the change of momentum divided by time. This is in contrast with solid-on-solid friction, which generally has very little flow velocity dependence. The drag force can also be specified as, formula_9 where, "P" is pressure
Mercy Multiplied Francesca Battistelli. Mercy Multiplied Mercy Multiplied is an international, Christian and charitable organization that offers a six-month residential program for young women aged between 13 and 28 who struggle with various "life controlling" issues such as eating disorders, depression, self-harm, abuse issues, and drug and alcohol addictions. The ministry operates as A Girl Called Hope in New Zealand. Mercy Multiplied has a pro-life stance in their faith-based approach, and as such, extend their program to offer women with unplanned pregnancies with alternatives to abortion, as well as treat women who identify as lesbian or who have sexual identity issues.
