Two oil tanks are connected by two 9-m-long pipes, as in fig. p6.26. pipe 1 is 5 cm in diameter and is 6 m higher than pipe 2. it is found that the flow rate in pipe 2 is twice as large as the flow in pipe 1. (a) what is the diameter of pipe 2? (b) are both pipe flows laminar? (c) what is the flow rate in pipe 2 (m3/s)? neglect minor losses.

What precautions should you take to prevent injuries when dealing with heavy loads?

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
