1.Three loads are applied to a beam. the beam is supported by a roller at A and by a pin at B. neglecting the weight of the beam, determine the reaction at A and B when P=15kips.
2.A process in a plant is to be revised such that the air flow rate through a system will increase from 8000 cfm to 10,000 cfm. The existing fan runs at 1600rpm and provides 6.0 in. H2O SP. Estimate the new speed required for this fan and the new SP (static pressure).
