Question - Water enter steadily from the base of a lawn sprinkler at 10-3 m3/s. The flow leaving each nozzle is in the tangential direction and the exit area of each of the two nozzles is 30 mm2 as shown in Fig. 3. The radius of the sprinkler arm is 200 mm, determine:
(a) The torque required to hold the arms stationary, Ts.
(b) The maximum rotation of the sprinkler, Ωmax in rpm.
(c) Plot the variation of torque, T with the sprinkler rotation, Ω. (ρw = 1000 kg/m3.)
find the MIN permissible SAG for a span of 225 m using a copper conductor with 1.2 cm diameter and allowing a MAX conductor tension of 2200 kg/cm^2 . The horizontal wind pressure is 6 g/cm^2 and specific gravity of copper is 8.9

A function f has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Derive the truth table for f. (b) Write the canonical sum-of-products expression for f.
There are three types of self-excited generators depending upon the manner in which the field winding is connected to the armature, namely;
Two statistically independent random variables, X and Y, have variances of sigma^2 (X) =9 and sigma^2(Y) =25. Two new random variables are defined as: U = 3X + 4Y V = 5X - 2Y (a) Find the variances of U and V.

The output of the transmitter is connected to a 50-? dummy load that has a calibrated average reading wattmeter. The wattmeter reads 6.9 kW. Find the PEP of the transmitter output.
Your circuit should output a signal X that can be used to turn a buzzeron or off, where high implies on. The buzzer should be on if theignition is on and if the door is open or the seat belt is notfastened. Draw your logic circuit and construct a ..
An 8x1 multiplexer has inputs A, B, and C connected to the selection inputs S2, S1, and S0, respectively. The data inputs I0 through I7, are as follows: I1 = I2 = I7 = 0; I3 = I5 = 1; I0 = I4 = D; and I6 = D'. Determine the Boolean function that t..
Design the datapath which has registers R0 through R3 and will output the value R0 + R1 if the value in register Z is zero and output R2 - R3 if the value in register Z is nonzero. Note: (Use any of the Basic datapath components and only use 1 adde..
