The phasor technique makes it pretty easy to combine several sinusoidal functions into a single sinusoidal expression without using trigonometric identities. however, you cannot use the phasor technique in all cases.
Select the expressions below for which the phasor technique cannot be used to combine the sinusoids into a single expression. check all that apply.
a.β100sin(10,000t+90β)+40sin(10,100 tβ 80β)+80cos(10,000t)
b.100cos(500t+40β)+50sin(500tβ120β) β120cos(500t+60β)
c.25cos(50t+160β)+15cos(50t+70β)
d.45sin(2500tβ50β)+20cos(1500t+20β)
e.75cos(8t+40β)+75sin(8t+10β)β75cos (8 t+160β)

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90Β° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90Β° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
