A pump station (el: 50-ft) is to use radial flow centrifugal pumps taking suction from a reservoir (el: 100-feet) to serve a community (el: 180-feet). All pipes are to be 24" DIP (C=130). The Pump Station is to be located 2,100-feet from the reservoir and discharges to a community one mile away. The community has an average daily demand of 22.5 MG. The delivery pressure to the community’s system must be 90 - 100 psi.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
