The flow around a model of a turbine blade is investigated. The model is five times larger than the prototype. A maximum pressure of 4 psi is measured at the leading edge, a maximum velocity of fps is measured near the top of the blade, and a small device attached to the surface measures a shear stress of 0.02 psi at a particular location. Determine the associated quantities to be expected on the prototype if water is the fluid for both cases.
the condensation that can occur in the low-pressure end of a steam turbine is undesirable because it can cause
A 1982 U.S. Department of Energy article (FS#204) states that a leak of one drip of hot water per second can cost $1.00 per month. Making reasonable assumptions about the drop size and the unit cost of energy, determine if this claim is reasonable. S..
