a horizontal 600mm diameter pipe carries 1.2m3/s liquid (relative density =0.82; dynamic viscosity =0.006Pa s). The pipe is connected to a 400mm diameter pipe by a concentric reducer, the gauge pressure at the entrance of the reducer is 3.00 bar and the the energy losses are neglected . Determine the restraining force.
Field tests have shown that the Horton equation best describes the composite roughness of the channel. Find the capacity of the main channel and the lateral extent of the floodplains for a 100-year flow of 1590m^3/s.
write computer code using Matlab that emoloyes the nelder and mead simplex method to solve the welded-beam design (benchmark problem
Calculate the average velocity (rnps), crosssectional area (rn"), and depth (m) for the stretch. To make these estimates, assume that the stretch can be idealized as a rectangular channel.
Given: elastic modulus of steel is 200 GPa, yield and ultimate tensile strength of steel are 600 and 750 MPa, respectively.
Estimate the median and 90th percentile load of SS contained in the runoff. Note: COV = coefficient of variance
A differential leveling loop started and closed on BM Juno, elevation 5194.02 ft. The BS and FS distancces were kept approximately equal. Readings (in ft) listed in the order takken are 9.65, 2.11, 2.51, 8.35, 2.06, 9.25, 7.93, 2.83, 5.05, and 4.6..
Two transmission belts pass over sheaves welded to an axle supported by a thrust bearing at B and a journal bearing at D. The sheaves A has a radius of 50mm, and the sheave at C has a radius of 40mm.
Determine the factors of safety against sliding and against overturning, and also the soil pressure at the heel and toe. Assume hydrostatic uplift varies uniformly from full hydrostatic head at the heel of the dam to zero at the toe. consider 1m l..
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate).
A fisherperson, pulling on the anchor cord, causes a force on the man of F=(40i+20j-50k)N. If the cord is 30m long,determine the Cartesian coordinates of the anchor at A. Assume that cord OA is a straight line.
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
The 20-kg mass is suspended from three cables. Cable AC is equipped with a turnbuckle so that its tension can be adjusted and a strain gauge that allows its tension to be measured. If the tension in cable AC is 40 N, what are the tensions in cable..
