10.33 Saturated steam at 0.2 bar condenses with a convec- tion coefficient of 6000 W/m²2 · K on the outside of a brass tube having inner and outer diameters of 16 and 19 mm, respectively. The convection coefficient for water flowing inside the tube is 5000 W/m². K. Esti- mate the steam condensation rate per unit length of the tube when the mean water temperature is 30°C.

A food product with 73% moisture content in a 10 cm diameter can wants to be frozen. The density of the product is 970 kg / m³, the thermal conductivity is 1.2 W / (m K), and the initial freezing temperature is -2.5 ° C. After 14 hours in the freezing medium -40 ° C, the product temperature becomes -10 ° C. Estimate the convection heat transfer coefficient of the freezing medium. Assume the can as an infinite cylinder. h = Answer W / (m² K).

Hot brine from a geothermal well passes through 120 3 cm-O.D., 1 mm-wall- thickness, 16 m-long titanium alloy (k = 14 W/m K) tubes. Refrigerant-113 boils on the exterior of the tubes at 150°C, with an outside heat transfer coefficient of 20,000 W/m² K. The hot brine enters the tubes at 210°C, and the bulk velocity in each tube is 2 m/s. Calculate the following quantities. (i) Rep, the Reynolds number inside a tube (ii) hei, the inside heat transfer coefficient (iii) U, the overall heat transfer coefficient

Transport Phenomena Question

A copper electric wire of radius R, = 1 mm is isolated by a layer of PVC so that the outer radius of the wire Rg = 2 mm, as shown in Figure below. The wire exchanges heat with the air at 20°C according to a heat transfer coefficient h=20 W/m2°c: Given that : k=copper electrical conductivity=4.0 × 1070hm-'m¯! kpvc= PVC thermal conductivity = 0.3- m°C kco = copper thermal conductivity = 100 m°C %3D (amp/m)² And that the electrical heating source is given by : S, amp²s /kgm³ If the temperature (T,) on the outer surface (r = RG) is 25°C, what is the electrical current C (amp) that passes through this wire? Dont forget to state your hypothesis clearly.     Hi, Could you please tell me what the book's name is? Thank you!
