7. A product containing 40 % solids at 10 /C enters a direct contact heat exchanger at the rate of 10 kg/s. Saturated steam (of quality 80%) at 350 kPa mixes with the product. The resulting mixture is separated into two streams. The first stream (by-product) leaves at 60 /C and the second stream (product) leaves at 30 /C at the rate of 5 kg/s with a solids content of 60%. Determine the mass flow rate of steam, mass flow rate of the first stream, and the solids content of the first stream. The specific heat of the solids is 3,000 J/kg K.

A treatment plant has been designed to achieve 99 percent inactivation of Giardia Lamblia using chlorine dioxide. The engineer used data on the disinfection of Giardia Lamblia at 20°C for the design, but the plant operates in a northern climate, and current estimates are that the low water temperature in some winters will be 0.5°C. Estimate the expansion required in the contact chamber in order to achieve the same inactivation at that temperature. You may assume complete mixing in the contact chamber and that the inactivation of Giardia Lamblia follows the Chick-Watson relationship. Ct values for achieving 90% inactivation of Giardia Lamblia (mg.min/L) Temperature (°C) 0.5 °C 5 °C 10 °C 15 °C Chlorine 0.97 0.63 0.48 0.32 dioxide * Note that the chick Watson's disinfection rate constant is a function of temperature. 20 °C 0.24 25 °C 0.16
2-64 Nitrogen enters a steady-flow heat exchanger at 150 kPa, 10°C, and 100 m/s, and it receives heat in the amount of 120 kJ/kg as it flows through it. Nitrogen leaves the heat exchanger at 100 kPa with a velocity of 200 m/s. Determine the Mach number of the nitrogen at the inlet and the exit of the heat exchanger.

A steam turbine is to operate on a simple regenerative cycle. Steam is supplied dry saturated at 40 bar, and is exhausted to a condenser at 0.07 bar. The condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. The resulting water which is at saturation temperature is then pumped to the boiler. For the ideal cycle sketch the process on the T-s diagram and calculate, neglecting feed pump work,The amount of bleed steam required per kg of supply steamThe thermal efficiency of the plantThe specific steam consumption
