Pleaase answer 1-2 in full long details. Thanks 1) How many flow channels (# of channels shown in sketch are representative and not actual) are available for flow on each side? - 2) Calculate (hydrodynamic) equivalent diameter of channel between the plates and flow rate per channel. Given: c. A counter flow plate heat exchanger is being used as regeneration section of a HTST to heat raw (unpasteurized) milk with hot pasteurized milk. The heat exchanger contains 41 plates. Each plate is 1.52 m high and 0.6 m wide. The gap between the plates is 3 mm. The raw milk at 20°C enters the heat exchanger at a rate of 2.5 kg/s. The hot milk counter currently enters at 75°C. In given temperature range, physical properties of milk are provided in table below: Property At 75 C At 20°C Viscosity, Pas 0.003 Thermal conductivity, W/m°c 0.64 0.56 Heat capacity, /KgC 3900 3900 Density, kg/ml 1030 RAW MKT. 0.001 1030 HOT MOUT,PERT!
