- Fast pls i will give u like for sure solve this question correctly in 5 min pls Consider a solid bar of length L with variable cross-sectional area given by A(x) , where x ∈ [0, L] is distance along the bar. If the sides of the bar are insulated and if A(x) varies slowly, it is reasonable to make an approximation in which the heat flows only in the x direction. Consider the rate of change of the total thermal energy between arbitrary positions x = a and b to derive a heat equation for the bar in terms of the temperature u(x, t) . You may assume the density, heat capacity and thermal conductivity are constant (i.e. constant thermal properties) and that there is no heat source.G1/ in the Pipe (A) is equal (PA= 25 Lit15), the diameter is equal ( DA - 75mm, Do = Fig.shown, the Flow rate in 6o mm, Dg = Dc%=30 mm), and the velocit Pipe (D) is equal (U0=5m/s), the relation between flow rate in Pipe (B) and pipe (c) %3D Find the Value af . 2- Un, UB, Uc. water Os = 30 mm input A QA - 25 Lit/sec = 75 mm fo mm %3D Inpud = A outPut = B,C,D accumule tion =o.Q3// A rotary filter is required for the filtration of a slurry to produce 10 m' in 3500 s, the pressure difference is a constant at 70 kN/m´ and 20% of the drum is submerged in the slurry.
