Heat transfer—A review of 2004 literature

Mashhad is one of the largest pilgrimage metropolises in eastern north of Iran. The current study has been done to identification of urban propaganda pathology in Mashhad city and improved the role of citizen's participation in promotion of urban landscape in the cast study region. Statistical society of this research includes 70 experts of Mashhad municipality. The majority of population are male (83.1%) and the overwhelming majority have BA degree (47.5%) with mean age of 33.48 and 8 years of experiences. Results showed that the most important factor in organizing and achievement of municipal propaganda is citizen participation. Also, this paper was presented some solutions to attract the citizen participation in Mashhad municipality programs. According to this fact, Mashhad municipality and other local organizations have to done the necessary planning for improving the urban landscape and take step towards desirable, effective and soothing environmental Graphic.

The Importance of Citizen Participation in Organizing Urban Propaganda (A Case of Mashhad city, Iran)

Criterial (dimensionless) relationships are proposed for the heat transfer from heating air to a tube wall, from a heat-transfer surface to cold air, and for the overall coefficient of heat transfer through the wall of a heated tube. The relationships were obtained from processing experimental data for a tube-in-tube heat exchanger of a large height.

An experimental investigation of heat transfer in an air-to-air heat exchanger

The dependence of the heat power of a pipe (air–air heat exchanger) on the flow rate and the temperature of the heating air is investigated experimentally. The temperature fields along the height of the pipe are measured. In the experimental velocity range 1.2–9.5 m/sec and heating-air temperature range 120–280°C, the heat power depends strongly on the temperature and negligibly on the flow rate of the heating air. Increasing the cold-air flow rate increases the thermal power in direct proportion.
