1. A bioinstrumentation manufacturer mixes four alloy feeds to continuously produce desired alloys to cast scalpels and other surgical equipment. a. Inlet Alloy Feeds 1, 2, 3 and 4 are combined in one mixing unit (see below). The Target Allow I outlet mass flow rate is 1000lbm/hr. F, G, H and K are hypothetical compounds. The weight fractions of components F, G, H and K in the Alloy Feeds and Target Alloy I are given in the table. Calculate the mass flow rates at which the four Alloy Feeds should be supplied to mix to produce the Target Alloy I stream.

For a different application, Alloy Feed 1 and 2 are combined in a mixing tank labeled mixer 1 (see figure). The weight fractions of components F, G, H and K in Alloy Feeds 1 and 2 are given in the table. The mass fractions of F in the outlet stream from mixer 1 is 0.5. The outlet stream from mixer 1 is then combined with Alloy Feed 5 in a second mixing tank labeled Mixer 2 to produce Target Alloy II. Allow Feed 5 contains only F, H and K; the mass fraction H is one-half the mass fraction of F. The mass fraction of F in Target Allow II is 0.4. In target Alloy II, the mass fraction of G is equal to the mass fraction of H. The Target Alloy II outlet mass flow rate is 1000 lbm/hr. Set up and solve mass conservation equations around mixer 1. Determine the mass flow rates of all streams and the mass fractions of all components in all streams entering and leaving mixer 1. Report the final answers so that the outlet mass flow of Target Alloy II is 1000 lbm/hr. Alloy Feed 5 Alloy Feed 1 Birger 1 Mixer 2 Target Alloy 11 Alloy Feed 2 2
