Suppose there are 4 routers in sequence between host a and host b, all of which use store-and-forward routing. what is the total end-to-end delay for a packet originating from host a with destination host b, under the following conditions.

(a) each of the link transmission rates are 9.1 mbps
(b) the total distance from host a to host b along its path of transmisison is 161.2 km
(c) the speed of propagation through the transmission medium is is 2.7 x 108 m/s
(d) the packet size is 4 kib

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k

A12 mm diameter shaft runs in a plain cylindrical bush 30 mm long that is located in an 18 mm diameter hole in a housing. the shaft-inner bush fit is h8 f and the outer bush-housing fit is h7-p6. make a fully cimensioned sketch of the bush with tolerances. find the maximum and minimum clearance or interference for both fits on the inner and outer diameters of the bush
