Chapter 7, Problem 7.48P

An L = 1 -m- long vertical copper tube of inner diameter D i = 20 mm and wall thickness t = 2 mm contains liquid water at T w 0 ° C . On a winter day, air at V = 3 m/s, T = 20 ° C is in cross flow over the tube.

  1. Determine the heat loss per unit mass from the water (W/kg) when the tube is full of water.
  2. Determine the heat loss from the water (W/kg) when the tube is half full.

Engine oil enters a circular tube D=10-cm in diameter and L=23-m in length. If the flow rate and inlet temperature of the oil are m=0.4-kg/s and Tm.i =18°C, find the thermal entry length (x,h =?) in the tube? Note: Use the following properties at mean temperature of the engine oil. H=0.50 N.s/m², v = 1.1 × 10-7 m²/s, Pr = 220
Water flows in a 3.5-cm-diameter pipe so that the Reynolds number based on diameter is 2000 (laminar flow is assumed). The average bulk temperature is 10°C. Calculate the maximum water velocity in the tube in m/s. (Recall that um = 0.5ug)
Determine the Height of a chimney with a static draft of 12 mm if the losses total draft is 4 mm, the ambient air temperature is 35 ° C and theexhaust gas temperature is 450 ° C. The fuel consumption of the boiler is 600 kg / h, the mass of the exhaust gas is 16 kg, also determine the air mass ma, the diameter of the chimney and the velocity of the exhaust gases.
