Hot brine from a geothermal well passes through 1203cm0.D.,1mm-wallthickness, 16m-long titanium alloy (k=14W/mK) tubes. Refrigerant-113 boils on the exterior of the tubes at 150C, with an outside heat transfer coefficient of 20,000W/m2K. The hot brine enters the tubes at 210C, and the bulk velocity in each tube is 2m/s. Calculate the following quantities. (iv) Ntu, the number of transfer units of the boiler (v) , the exchanger effectiveness (vi) TH,out, the hot stream outlet temperature For the brine, take k=0.6W/mK,=900kg/m3,cp=4000J/kgK, and v=0.20106m2/s; for R-113, take hfg=0.2106J/kg Hot brine from a geothermal well passes through 1203cm0.D.,1mm-wallthickness, 16m-long titanium alloy (k=14W/mK) tubes.
