Question

Superheated steam at T1°C and 20.0 bar is blended with saturated steam at T2°C and 10.0 bar in a ratio (1.96 kg of steam at 20 bar)/(1.0 kg of steam at 10 bar). The product stream is at 250°C and 10.0 bar. The process operates at steady state. Calculate T1 and T2, assuming that the blender operates adiabatically.

Answer 1

To solve this problem, we can use the First Law of Thermodynamics and the steam tables to find the temperatures T1 and T2.

Step-by-step explanation:

To solve this problem, we can use the First Law of Thermodynamics, which states that the total energy of a system is conserved. The energy balance equation can be written as:

Mass of steam at T1 * enthalpy of steam at T1 + Mass of steam at T2 * enthalpy of steam at T2 = Mass of product stream * enthalpy of product stream

Using the given data and the steam tables, we can find the enthalpy values for the steam at T1, T2, and the product stream. Then we can solve the equation for T1 and T2.
