A steam stream of 400 m3 /s, standard (standard cubic meter per second) is cooled by adding 7 m3 /s cold water. The fluid leavin

antiseptic1488 [7]

Answer: 510 m/s

Explanation: specific gravity of steam is 18/29 = 0.620

It is the ratio of the density of steam over density of water

400m3/s of steam =

400m3ms * 0.620 of water

= 248m3/s of water

Total flow rate Q = 248 + 7 = 255m3/s

Using Q = AV

Where A is area and V is velocity

V = Q/A

V = 255/0.5 = 510m/s

Block 2 of mass 1.00 kg is at rest on a frictionless surface and touching the end of an unstretched spring of spring constant 20

son4ous [18]

Answer:

x = 0.327 m

Explanation:

Block 2 of mass 1.00 kg is at rest

spring constant = 200 N/m

Block 1 of mass 2 kg moving at 4 m/s

m₁ v₁ = (m₁ + m₂)V

2 x 4 = (2 + 1) V

V = 2.67 m/s

loss of kinetic energy = gain elastic potential energy

$\dfrac{1}{2}mv^2 = \dfrac{1}{2}kx^2$

$\dfrac{1}{2}\times (3)\times 2.67^2 = \dfrac{1}{2}\times 200 \times x^2$

x = 0.327 m

hence, the spring compressed distance is equal to x = 0.327 m
