Several methods are used to estimate kinetic energy, being the majority, based on rain intensity. This research presents a new method able to measure the drop velocity, designated as Dynamic Rain Gage System (DRGS). Simulated rains were investigated even under windy conditions to measure the ...
Sprinkler kinetic energy has been linked to a number of problems in irrigated fields. This work presents the characterization of sprinkler drop kinetic energy and specific power from low-speed photographic drop data using a commercial impact sprinkler and three operating pressures. The spatial variabilit...
The existence of an optimal velocity (Vopt) in the higher than ordnance velocity range, for constant kinetic energy constant L/D long rod projectiles, is a crucial factor to understand the potential consequences of hypervelocity military launchers. Frank and Zook [1] have shown how to obtain Vo...

In 1824, this reaction was recognized to be crucial for the function of the Davy safety lamp, and today it is used to optimize combustion, hydrogen production and fuel-cell operation. The carbon dioxide products are formed in a bimodal kinetic energy distribution; however, despite extensive ...
The role of the tip-vortex pairwise instability ("leapfrogging") is investigated in relation to the process of kinetic energy transport and turbulence production within the shear layer of a horizontal-axis wind-turbine wake. Experiments ... LE Lignarolo,D Ragni,CS Ferreira,... - Asme Wind ...
We have used the technique of Q-switched ruby laser vaporization of thin metal films to obtain the velocity dependence of the reactive cross section for Pb + N2O PbO(B, v′ = 0) + N2 for kinetic energies in the vicinity of the thermodynamic threshold up to 3 eV (in the center of mas...
Can an object have both kinetic and gravitational potential energy at the same time? Yes, an object can have both kinetic and gravitational potential energy at the same time. For example, a roller coaster at the top of a hill has gravitational potential energy due to its height and kinetic ...
A semblance is a quantitative measure of the coherence ofseismic datafrom multiple channels that is equal to the energy of a stacked trace divided by the energy of all the traces that make up the stack. If data from all channels show continuity from trace to trace, the semblance has a val...
