You are assigned to determine the maximum design axial load strength of a short, circular column, having a diameter of 18 in. and reinforced with No.9 longitudinal bars. The cover is 1.5 in. and the spiral is No.3 bar spaced 2 in. o. c. Use f'c=3,000 psi, and fy=40,000 psi. 1- What is the maximum design axial load of the above-mentioned column? 2-How much additional axial strength could be provided (in percentage) by using a fy=60,000 psi steel?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
