Q1: 1: Design the critical section for span 1 & 11 of the reinforced concrete one way slab bridge. Consider the span lengths in meters and the live load according to the data shown in the following table. Useful Data Width = 7.2 m Asphalt weight 1 kN / m2 Handrail weight = 1 kN / m Seat width = 400 mm - f = 25 MPa Ty = 410 MPa - T = 25 kN / m3

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
