The motion of a liquid in an open tank is that of a combined vortex consisting of a forced vortex for 0 2 ft. The velocity profile and the corresponding shape of the free surface are shown in Fig. 6 . The free surface at the cen- ter of the tank is a depth h below the free surface at r = o. Deter- mine the value of h. Note that h = hforced + h&ce Where hforced and hfee are the corresponding depths for the forced vortex and the free vortex, respectively. 8-

0.56 kg of water in a piston cylinder device as shown initially the water is at T, = 120 °C with volume V, = 36 L (State 1). Heat is then added such that all the water in the cylinder is saturated vapor and the piston just touched the spring without exerted any force on the spring (State 2). Then additional heat is added to the system such that the temperature is T, 600 °C and the pressure is P,= 400 kPa (State 3). 3 Po 3 1) Find the total work (from state 1 to state 3, in kW).

kg). Q3. The steam at 215 bar and 500 °C is supplied to a steam turbine. It expands to 40 bar and 280 °c. It is then reheated to 490 °C and expands to 8 bar and 270 °C. The steam coming out from the second expansion of the turbine is further reheated to 490 °C and expands to condenser pressure of 0.07 bar. The steam entering into the condenser is dry saturated.
