After going through the production process, thin plates with a length of 0.9m arecooled by suspending them vertically in an atmosphere of quiescent hydrogen at 80°C.To maximize production throughput, the plates are hung as close together as possible.There is a concern however, that if the plates are too close together, the cooling willtake longer, costing the company additional money.If the plates are initially at a temperature of 110°C, what is the minimum plate spacingthat would avoid interference between their free convection boundary layers?Thermos-physical properties are shown in the table below.Thermal Diffusivity [m2/s]2.446*10-4Kinematic Viscosity [m2/s]1.573*104Prandtl Number [-]0.6969

So, the plates should be spaced at least 23.5 mm apart. I HOPE THIS WILL HELP YOU 🙏.IF YOU NEED ANY…

Hot isostatic pressing is to be used to produce the femoral head components of hip implants made from a novel grade of zirconia. A series of manufacturing trials have demonstrated that the processing route results in post-sintered surface features 43- 107 μm (mean 74 µm) in size. In clinical use it is anticipated that the femoral heads will be loaded to maximum stress level of 50% of its tensile strength once implanted. What is the critical flaw size when in service and will the implant require polishing for it to withstand loading during clinical use? Where: .
