Why does CT in powerplants have hyperboloid shape? The reasons are listed below 1. Strength factorFirst and foremost, the hyperboloid shape impacts the strength of the entire structure. Since #CT are supposed to cool the working fluid down to a low temp., they release vapors into the atmosphere through the opening at the top of the tower.Therefore, these towers have to

When to start the pump with discharge valve open ? 1. Usually we need to start the pump with discharge valve closed. because if we start the pump at rundown point, power requirement is very high. And possibility of tripping of pump or burning of motor. Where specific speed is less than 2000.2. If the

What is Process Design Engineering? Process design engineering is the application of chemical, mechanical, petroleum, gas and other engineering disciplines to the process-related development, planning, designs, and decisions required for economical and effective completion of a process project. An engineering project generally involves closely coordinated efforts of a multi-disciplinary team. Hence in addition to technical
