Answer the following: a) Your 1.00L water bottle is half-filled with warm water at 18C. To make it colder, you pour 360mL of cold water at a rate of Vin(smL)=20t0.5, where time t is in seconds. Make sure to draw a flowchart and wrile assumptions. i. What a the units of the constant " 20 " in the equation for flow rate in? ii. How much time is required to feed all the cold water? iii. What is the mass flow rate at the time you calculated above? b) To find temperature of a solid ( Tsolis) ) subjected to heat transfer only by radiation from a surface at a higher temperature (Tsurr), the following equation is used: VcpdtdTsolid=5.67108A(Tsurf4Tsollid4) i. Find the units for the constant 5.67108 in the equation. ii. Find the value of the "new" constant if the units of density are given in lbm/ft3 and area is given in ft2. c) Complete combustion of carbon disulphide (CS2(e)). i. Write the balanced reaction for complete combustion of CS2(). ii. Find Hro for this reaction, given the following: iii. Compare the value for Hc given in Table B.1 of text (Formula sheet)
