An insulated stream of warm water is produced in a steady flow mixing process by combining 1 kg/s of cold water at 25 oC with 0.8 kg/s of hot water at 75 oC. What is the temperature of warm-water stream ? what is the work of the mixing process, , and ? assume the specific heat of water is constant at 4.18 kJ/kg.K.

2) Operating a steady-state, a well insulated mixing chamber receives two input liquid streams of the same substance but with temperatures T1 and T2 and mass flow rates m ̇ 1 and m ̇ 2 respectively. The streams are mixed in the chamber, exiting as a single stream with T3 and m ̇ 3. Assuming the substance is incompressible with constant specific heat C, that potential energy, kinetic energy, and pressure changes are negligible, obtain an expression for a) T3...

Two streams are mixed to form a single stream. Only the steady flow in the mixed stream is known. A soluble salt is added to one of the original streams at a steady state and samples show the stream to have a 4.76% salt content by weight. Samples of the combined stream show it to be 0.62% salt content by weight. What is the flow rate of the two original streams ?

In the process of methanol production, a gas stream flowing at a molar flow rate of...

In the process of methanol production, a gas stream flowing at a molar flow rate of 100 mol / min containing 32 mol% CO, 64 mol% Hz. and 4 mol% of N2 is led to the reactor. The product from the reactor is condensed where liquid methanol is separated. Unreacted gases are recycled in a ratio of 5: 1 mol of recycle to moles of fresh feed. Parts of the recycled gases are purged. The reaction equation is CO +...

A food processing plant makes soup in a continuous process with a steady flow of product into and out of a large kettle. The soup is maintained at a certain temperature by heating the kettle with a coil of steam pipes. The large size of the kettle means the entering product remains in the kettle for a long time. Draw a graphic and describe how the plant could use feedback, feedforward, and cascade control to maintain a constant temperature. Which...
