A beam is to be designed for loads causing a maximum factored shear of 60.0 kips, using concrete with fc′ = 5000 psi. Proceeding on the basis that the concrete dimensions will be determined by diagonal tension, select the appropriate width and effective depth a. for a beam in which no web reinforcement is to be used.
b. for a beam in which only the minimum web reinforcement is provided
c. for a beam in which web reinforcement provides shear strength Vs = 2Vc.

Follow the ACI Code requirements, and let d = 2b in each case. Calculations may be based on the more approximate value of Vc.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
