An approach to a signalized intersection has a saturation flow rate of 1800 veh/h. At the beginning of an effective red, there are 6 vehicles in queue and vehicles arrive at 900 veh/h. The signal has a 60-second cycle with 25 seconds of effective red. What isthe total vehicle delay after one cycle?

When it comes to making a good impression in a work setting, it does not apply to an initial contact, since both people are meeting for an express purpose. you have a 5 to 10 minute grace period before people form their impression of you. your handshake and facial expression dominate all other elements of your appearance. you have only seconds in which a person will accept or reject an employee or firm.

The velocity, c, at which pressure pulses travel through arteries (pulse-wave velocity) is a function of the artery diameter, D,and wall thickness, h, the density of blood, p, and the modulus of elasticity, E, of the arterial wall. Determine a set of nondimensional parameters that can be used to study experimentally the relationship between the pulse-wave velocity and the variables listed. Form the nondimensional parameters by inspection.
