The paper proposes an experimental and numerical approach of analyzing on the influence of working fluid and mass flow rate on the heat transfer characteristic in plate heat exchanger by performing the experiment on an industrial counter flow plate heat exchanger with 59° chevron angle. In this study, numerical results obtained from Aspen HYSYS V10 Exchanger Design and Rating EDR were compared with experimental data and showed good arrangement. The effective heat transfer area is 4.2 m2. Water is used as cold fluid and oil is used as hot fluid with the counter flow arrangement. Cold water flow rate is controlled at different flow rate of 2 m3 hr, 4 m3 hr and 6 m3 hr. Hot oil flow rate is varied from 3.6 m3 hr to 5.2 m3 hr. The inlet temperature of cold water and hot oil to heat exchanger were kept constant at 50°C and 32°C respectively. The experimental and numerical results show significant effect of flow rate on heat transfer rate, overall heat transfer coefficient, and effectiveness. It is shown that the Aspen HYSYS V10 EDR is a reliable tool for investigation of heat transfer characteristic in the plate heat exchangers at various flow rate. 

This paper describes the design and fabrication of runner blades for cross flow turbine is presented. In this paper, the cross flow turbine's runner is designed to produce 100 W electric powers from head of 4 m and the flow rate of 0.004 m ^3 s. For the given capacity and head of the turbine, the dimensions of runner diameter and width 265 mm and 132 mm is obtained respectively. The detail design calculation of the runner is described in this thesis. It is applicable to wide range of flow rate adjusting the runner length. The term hydropower refers to shaft power generated by converting potential and kinetic energy of power. By using water power, the generation of electrical power is well known and widely used throughout the world. In hydropower plant, water turbine is one of the most important parts for generating electricity. This paper is to fulfill the required electricity in rural area. 

This paper describes the design and construction of the pedal operated water pump are done especially discharge rate at different speed and height. The proposed pump is a rotary pump operated by pedal power. In the rotary pump, water enters axially through the vane eyes and exits radially. In this paper, necessary dimensions are calculated for the design point of 6.096 m 20 feet height, 0.00018 m3 sec flow rate and rotational speed 260 rpm. Pedal operated water pump is purposed to use in small irrigation and garden irrigation and drinking water where electricity is not available. 

Tidal energy is a largely untapped, renewable energy source based on lunar gravitation rather than solar radiation. The generation of electricity from tides is very similar to hydroelectric generation. Tidal energy is clean and not depleting. The tidal schemes may be of single pool or double pool or multi pool. Two types of tidal power plant are barrage style tidal power plant and tidal current power plant. Among them, barrage style tidal power plant was chosen to suit local condition and facilities in Myanmar. Several different turbine configuration are possible. The propeller turbine designed is based on tidal head and flow rate of Kanbalar Creek. The maximum and minimum head of tidal range is 5 m and 2 m. The available flow rate is 0.46 m3 s. The type of turbine is chosen by using 2 m head and 0.46 m3 s flow rate. Therefore, 3 kW propeller turbine is designed in this paper. Then, calculated runner diameter is 280 mm, hub diameter is 112 mm and number of blade is four. Two dimensional blade profile is calculated by using MATLAB program software and drawn AutoCAD software.
