WebApr 13, 2024 · As shown in Table 1, the turbulent kinetic energy of each characteristic head is compared. It can be seen that with the rise of the head, the flow rate decreases, resulting in the decrease of the turbulent kinetic energy. However, the change of the …
WebThis lack of conservation means that the forces between colliding objects may remove or add internal kinetic energy. Work done by internal forces may change the forms of … WebOct 1, 2024 · When the change in kinetic energy is zero we have Δ K E = K f − K i = 1 2 m v f − 1 2 m v i = 0 which, after multiplying by 2 and dividing by the mass, gives v f = v i. The work-energy theorem says F net s = K f − K i but since v f = v i, the right hand side is zero, and so the left hand side, F net s, is zero.
WebSince friction is always an opposing force you subtract this from the 38.5KJ and get the 8455J mentioned. This is the kinetic energy so 1/2mv^2 and you then multiply both sides by 2 and get 16910 = mv^2. The mass is 90kg so divide both sides by 90 and get v^2=187.8889. Square root this and you end up with 13.7m/s. WebApr 18, 2024 · The internal energy of an ideal gas consists of only kinetic energy. If work is done on the gas energy is added to the gas. That means the internal kinetic energy has to increase. And since the internal energy of an ideal gas depends only on temperature, that means the temperature has to increase. Hope this helps.
