Explanation:
From the question we are told that
The initial speed of the hot water is 
The pressure from the heater 
The height of the hot water before flowing is 
The height of bathtub above the heater is 
The pressure in the pipe is 
The density of water is 
Apply Bernoulli equation

Substituting values

=> ![v_2^2 = \frac{ (450 *10^{3}) + (1000 * 9.8 *0 ) + (0.5 * 1000 * 0.85^2) -[ (1000 * *9.8*3.70) ]}{0.5*1000}](https://tex.z-dn.net/?f=v_2%5E2%20%3D%20%20%5Cfrac%7B%20%28450%20%2A10%5E%7B3%7D%29%20%2B%20%281000%20%2A%209.8%20%2A0%20%29%20%2B%20%280.5%20%2A%201000%20%2A%200.85%5E2%29%20-%5B%20%281000%20%2A%20%2A9.8%2A3.70%29%20%5D%7D%7B0.5%2A1000%7D)
=> ![v_2= \sqrt{ \frac{ (450 *10^{3}) + (1000 * 9.8 * 0) + (0.5 * 1000 * 0.85^2) -[ (1000 * *9.8*3.70) ]}{0.5*1000}}](https://tex.z-dn.net/?f=v_2%3D%20%5Csqrt%7B%20%5Cfrac%7B%20%28450%20%2A10%5E%7B3%7D%29%20%2B%20%281000%20%2A%209.8%20%2A%200%29%20%2B%20%280.5%20%2A%201000%20%2A%200.85%5E2%29%20-%5B%20%281000%20%2A%20%2A9.8%2A3.70%29%20%5D%7D%7B0.5%2A1000%7D%7D)
=> 
A birds feather. Because a birds feather is way lighter than a model rocket, so it wild go down slower, in a waiver motion.
