The cooling performance of an externally mounted, flat-woven, black-polypropylene shade cloth (manufacturer’s shade rating of 55%) was examined under both dry and wet conditions. Wetting was accomplished by intermittently sprinkling the cloth with

The cooling of two naturally ventilated (nv) and two fan ventilated (fv) greenhouses were compared over two summers. Air temperatures and relative humidities in and above the canopy and leaf temperatures were measured. The nv houses used fogging nozz

The Penman-Monteith equation has been used to describe the transpiration of greenhouse crops; however, it generally requires re-parameterization for each dataset, restricting the robustness of the equation for predictive purposes. This paper applies

Tests were conducted to examine the role of cloth temperature in the cooling efficiency of shade cloths applied to greenhouses. In the first test, shade cloths (with two thermocouples attached to each) were laid over a pair of small wooden frames, su

A nonlinear differential equation was used to model the contact force of the rebounding blueberry. Model parameters were determined by a least squares curve fitting algorithm resulting in correlations of 0.98 for model mass with berry mass and 0.62 f
