. A creep test was performed on a wire where the increase in percent strain (e) overtime (t) as a constant load is applied is measured as follows:time (min): 1.587 3.088 4.590 6.091 7.592 9.094% strain: 0.08 0.15 0.20 0.29 0.35 0.42Determine the linear relation between percent strain and time. What will be thepercent strain: at 12 minutes? [note: e = k t]

2. A source of gamma rays was employed to give measured doses of radiation in anexperiment. However, the dosage varied with position in the apparatus as shownby the data:position from base point, x (inch): 0. 0.5 1.0 1.5 2.0 3.0 3.5 4.0dosage, d (105 rads/hr): 1.90 2.39 2.71 2.98 3.92 4.20 4.56 4.88Generate the linear equation and calculate the missing dosage level at x = 2.5Inch3. By measuring the water flow depth (h) over a rectangular weir of width (B) thevolume flow rates (Q) in a channel can be calculated using the following weirequation:Q (ft3/s) = [ Cd ( 2 ) B ] hn (B, h in ft units)Determine the values of Cd and n based on the following laboratory test data for aweir of width 6 inches (g = 32.2 ft/sec2).[note: ln(Q) = ln[ Cd ( 2 ) B] + n ln(h)Q (ft3/min): 161 123 87 56 30 11h (inch): 12 10 8 6 4 24. Andrades equation relating viscosity, (N.s/m2) with temperature, T (K) for liquidsis given by(1/) = Develop Andrades equation for water using the following data:[note: ln ( ) = ln (D) + B (1/T) ]temperature, T (oC): 0 20 40 60 80 100viscosity, (N.s/m2x10-3): 1.787 1.002 0.6529 0.4665 0.3547 0.2818Estimate the viscosity of water at 30 oC and calculate the percent true errorbased on the true value 0.797510-3 N.s/m2.
