unit of credit as equal to a minimum of three hours of work per week for a semester. California's Title. V code, section 55002, also defines student credit in this way. While the length of a semester may vary, the Carnegie definition is based upon a minimum length of. 16 weeks. Thus, a unit of credit equates to three hours of student work per week (1 hour lecture plus. 2 hours of homework or 3 hours of lab) for 16 weeks. In certain circumstances, it is possible to have.
The velocity fuse is designed to stop hydraulic fluid, which is being used to hold a hydraulic cylinderâs load â in your case, the elevated lift should a hydraulic hose, tube, or seal rupture. When a hydraulic fluid line breaks, the fuse detects this and closes blocking fluid from exiting through the break.
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.
