Ricci Martin Dies: Entertainer & Youngest Son Of Dean Martin Was 62. Ricci Martin, the youngest son of musical legend Dean Martin and a musician & entertainer in his own right who most recently performed in a touring tribute to his father died Wednesday in his home in Utah. His family made the news public today; no cause of death has yet been determined.
The hoods ensure uniform air distribution and impingement velocity across the sheet for highest drying rates and a good moisture profile. The constant distance between the nozzle and the paper or board enables optimum heat transfer. Drying temperatures go up to 400Â° C and impingement velocities up to 130 m/s.
Increased velocities produce higher duct friction losses. In order to maintain flow against the higher duct friction, it is necessary to have greater pressures at the air source. Therefore, the terms âhigh pressureâ and âhigh velocityâ generally go hand in hand. Conversely, this is true of âlow pressureâ and âlow velocityâ. The use of the terms âhigh velocityâ and âhigh and medium pressureâ in this catalog refer to any static pressure class of 3â³ wg or greater, and âlow pressureâ refers to 2â³ wg or less. SMACNA recommendations on pressure and velocity are shown in the table below.
